Car Seat Basics

Whether you’re a brand new parent or have a minivan full of Littles, it can never hurt to review the basics of car seat safety. Take a few moments to check all of these in regards to your child’s car seat – it might just save their life.


harness height

Harness should be at or above for forward facing and at or below for rear facing

Are the straps at the correct height?

When using a 5 point harness, the straps should be positioned at or below the child’s shoulders for rear facing; at or above the child’s shoulders for forward facing.






Chest Clip

Chest clip needs to be positioned over the child’s sternum


Is the chest clip positioned properly?

The chest clip is designed to keep the straps in position over the torso before a crash happens. It must be placed on child’s sternum, at his nipple or armpit level.






pinch test

Harness must always pass the pinch test


Are the straps tight enough?

Do the pinch test: pinch the straps vertically at the collar bone. If you can grab excess slack between your fingers and pinch it, the straps are too loose.






belt path

Check for less than 1 inch of movement side to side at the belt path

Is the seat installed tightly?

Your car seat should be installed so that there is less than 1″ movement side to side, and front to back when grasping at the belt path. That means where the seat belt or lower anchor connector strap feeds through the car seat. That is the only place you need to test for movement, not the top of the car seat.







Tether should be used for all forward facing car seats

Is the tether attached?

When installing a forward facing harnessed car seat, always use a tether if one is available. The tether reduces forward movement for  the child’s head and neck up to 6″ in a crash; so reconfigure seats if necessary so all forward facing kids are in a vehicle seat with a tether anchor.







Is your child in the right stage of seat?

Is your child in the right stage for their age?

Kids should ride rear facing until a minimum of age 2, ideally 3-4 years old; forward facing in a 5 point harness until 5+ years old, and in a booster seat until 10-12 years old.







All seats have expiration dates anywhere from 4-12 years after they were manufactured

Have you checked the date?

Car seats expire anywhere from 4-12 years from the time they were manufactured. This time frame varies depending on the manufacturer, but plastics break down over time and an expired car seat may not protect your child adequately in a crash. Read more about car seat expiration here.








Nothing bulky should go under the harness, even in winter


Have you removed coats before buckling?

Bulky coats put extra space between the child and the harness which will compress immediately in a crash and mean more distance the child’s body moves before coming to a stop. Remove coats before buckling up, they can be worn backwards over the harness, or use blankets in the car instead. Read more about safe winter options for the car here. 






Many seats should be replaced after a crash, even a minor one

Have you been in a crash?

Chances are, even if the crash was minor, and even if the children were not in the car, the car seat(s) may need replacing. Check your car seat manual to determine the rules for your seat. You can find more information about accidents and replacing your seat(s) here. 







Reading the manual for your car seat is a very important step

Have you read the manual?

We know, we know. The manual is long, it’s boring, it’s full of warnings…. but we promise, this manual is one you must read. Your car seat’s manual holds the keys to making sure your child is as safe as they can be in your vehicle. It’s worth the read. If you have misplaced your manual, contact the car seat manufacturer for a replacement right away.




These are just a few important items to note when selecting and installing the correct seat and harnessing your child in that seat. CSFTL always recommends reading the car seat and vehicle manual prior to using any seat, and visiting a CPST in person whenever your child is moving to a new seat, a new vehicle, or the next stage.

Child Passenger Safety Dictionary

Whatever the reason for your interest in child passenger safety, there are many terms that you’ve likely never heard before, and will only hear when you’re talking about child passenger safety. Car Seats for the Littles wanted to compile a resource to help understand this secret language. This is definitely not exhaustive, but it is a good start.



AMP-snuzzlerAfter Market Products (AMPs): 

The technical term for these products is “non regulated products”- which means they are not regulated by any Federal Motor Vehicle Safety standard. Non regulated products are anything added to a car seat that did not come with the seat and has thus have not been crash tested with the seat; including head and body supports, harness strap covers, seat covers, toys, and many other items.

This is a term used to describe the installation of a car seat in a center seating position that does not have dedicated lower anchors, thus, “borrowing” one lower anchor from each outboard seat. Both the car seat manufacturer and vehicle manufacturer need to approve this type of installation.










When a rear facing car seat is putting pressure on the vehicle seat in front of it.  Most vehicle manufacturers and car seat manufacturers do not allow this type of installation.

Read the Car Seat Manual!

Read your car seat manual!

Read your car seat manual!

Everything you purchase comes with a manual, whether it is a lawn mower or a DVD player. When you are preparing for a child, multiply that by a bouncer, a high chair, a stroller and a swing.  Chances are, you read them to know how to put them together and their basic function.


After the initial assembly, the manual is likely to get thrown in the trash or lost in the dark abyss of a junk drawer, never to be seen or heard from again. There are two manuals that should be saved from the dark abyss and should be accessible at your fingertips. Those two vitally important manuals are your car seat manual and your vehicle manual.


When it comes to installing your child’s car seat, these are two very necessary items to ensure that it is done correctly. The top 5 questions that parents ask technicians about any specific seat would be the following:

  1. How do I install it?
  2. What are the limits of the seat?
  3. How do I wash the cover?
  4. When does it expire?
  5. Should I use LATCH or seatbelt?

One thing that is important to remember is that the knowledge of a tech is not a replacement for the information that is given in your manual.  Some technicians may remember the specifics of certain seats and be able to help you with that, however, our main goal is to educate.  We want to educate and empower you to know how to find that information themselves, feel confident in your ability to install a seat properly, and how to choose a seat
that fits your child correctly. All of the questions above can be found easily within the manual that came with your seat.


Car seat manual Table of Contents

Car seat manual Table of Contents

So lets look at question one.  How do I install it?  Since there are a variety of installation methods, this will be found in a variety of places throughout the manual, depending on which installation method and position you will be using your seat in.  The picture below was taken from an Evenflo Maestro Manual.  It lists the different types of installations and which pages those installation guides can be found on.

Car seat manuals will always have the weight, height, and age guidelines for the seat

Car seat manuals will always have the weight, height, and age guidelines for the seat

Second question up on the block: what are the limits of this seat?  This is generally located in the beginning of the manual with an overview over the entire seat, and then again within the
section for that feature of the seat.
The manual may even include visual pictures of how the seat should fit the child while in the seat.


Question number three brings us to washing, or caring for the seat.  This is a very important topic, because each seat may require different care.

Car seat manuals also contain cleaning information for the seat

For one seat the cover may be machine washable, but another may be spot clean only.


Question four steers us into discussing the expiration on your seat.   Learning that your seat expires may be new information for some parents. However, every seat on the market does expire.  The dates may vary from 5-10 years and some seats that are combination seats might have different expiration dates on the harness and the booster portion.  The date of manufacture will likely not be in your manual, that will be found on your seat, but an explanation of how long the seat is good for will be within the pages of your manual.

Car seat manual has information on the lower anchor limits as well

Look for warnings about lower anchors in the car seat manual

Look for warnings about lower anchors in the car seat manual

When LATCH, or lower anchors and tethers for children was introduced in the early 00’s, it was supposed to make installing child restraints easier, however, that is not always the case.  There are weight limits that go along with the use of lower anchors.  In early 2014, new regulations were introduced limiting the use of lower anchors to 65 pounds when the child’s weight and the car seat’s weight are combined.  All of the changes to LATCH are explained in our LATCH change post, found here.

That covers the top five questions that caregivers ask. The manual that comes with your car seat contains much more than that though.  Traveling?  You’ll need to know whether or not you can use your seat on the plane.  That can be found in the manual too!

Look in the car seat manual for FAA approval and installation instructions for airplanes

Going out in the cold? The manual addresses that as well. Telling caregivers to forgo the thick and bulky coats is not something that we make up to make life more difficult.

Car seat manuals include information on bulky clothing and harnesses

Worried that your child doesn’t have head support or covers on the harness straps? Again, telling parents to forgo these items isn’t something technicians say for fun.  These directions come directly from the manufacturers.

Lost a part? The contact information for the maker of the seat is located within the manual as well!

Car seat manuals include warnings and contact information in case of lost or broken pieces

Technicians are here to help and to educate parents.  Car seats can be confusing and the manufacturers understand that.  They may even include information about finding a technician near you for assistance!

Car seat manuals can help you find a local CPST

What about your vehicle manual? The one that you got with your new car and has sat in your glove box collecting dust? That can also be full of useful information about installing car seats!

Not sure what to do with your car seat when you don’t have it secured or have a child in it? The manual will tell you.

Car seats manuals can give information on what to do with unoccupied seats

Not sure how to lock the belt in your car? The manual will address that as well.

Lock your seat belt per your vehicle manual

Don’t be afraid to employ your most powerful arsenal when installing your child’s seat. The manual is a wonderful thing!  If you find yourself miss your manual, don’t panic!  Most manuals can either be found online or can be obtained by calling the manufacturer.   Once you are in possession of this precious book of information, keep it in a place that is easily accessible, such as your vehicle glove compartment.

Child Fit
If using this seat with newborns, it is highly recommended to use the lower birth weight fit kit.  It wasn’t available when this Little was born and I found the seat to be a bit big for her.

Orbit infant fit collageThe model on the left  was 2 days old, about 7.5 lbs and 21 inches long.  She just barely came to the bottom harness slot and had to use a rolled receiving blanket behind the crotch buckle to take up the extra room.  I found after using it for about a week that the infant head support that came with it actually caused her head to drop down to her chest, so I stopped using it and put rolled receiving blankets in it’s place.
Orbit harness comfort pads



I also found the harness comfort pads to be way too thick on her little body, so avoided using those as well.


Orbit low weight kit collage


The lower birth weight fit kit became available when she was about 2 months old, and 10 lbs.  It includes an under upholstery foam insert to raise the infant up, 2 side bolsters to take up the extra room on either side of the infant, and a smaller chest clip.  The bolsters and foam from the lower birth weight fit kit is designed for infants weighing 4-11 lbs.  The chest can be used as long as needed.  I found the fit to be pretty awkward with my 2 month old, but it might have worked better for a smaller infant.



Orbit older infantThe infant fit in the seat was great as this Little grew.  She’s a peanut, so it took a bit for her to fit well in it.  Here she is at 8 months, 15 lbs, and 27 inches.    I kept the smaller chest clip on the rest of the time we used the seat due to her narrow shoulders.  Orbit baby allows the use of each of the lower birth weight fit kit pieces individually as needed.  She still had several inches above her head.  It was a little more difficult to use the Paparazzi Shield at this point due to her feet going past the end of the car seat though.


Orbit seat features collage


The Orbit has several unique car seat features including a nice big canopy with a Paparazzi Shield that stores rolled up in the canopy and attaches to the bottom of the seat with elastic.  I loved this feature in the rain, snow, and wind.  The soft carry handle was helpful when carrying the heavy seat on your arm.  The seat also has an easily removable cover as well that can be removed without needing to take the harness out.



Car seat Installation
Installation was very simple with and without the base.  I installed it in a 2007 Kia Rondo with no issues at all.

Orbit StrongArm collage

The StrongArm technology consists of a knob at the front of the car seat that when it’s turned, it pushes a bar/arm into the seat back to tighten the base up against the vehicle seat.  Requires much less force than tightening manually.  The StrongArm can be used with both  lower anchor and seat belt installs.

**Important note about the StrongArm – There is a recall on the base due to the StrongArm detaching or failing to tighten.  To find out more please check our recall notice.**

Orbit lock off collage


The base also has a seat belt lock off so you don’t have to lock the seat belt.  The lock off works well and is very easy to use.


Orbit rotating hub collage


The most unique feature of this car seat is the rotating hub on the base and seat.  You can dock the seat in any position then turn it into the rear facing position.  I found this feature nice when keeping the seat in the car and just taking the baby out of the seat.  It can rotate 180 degree on the base so it’s not possible to turn it into a forward facing position. There is a window on the base that shows red when it isn’t clicked into the correct rear facing position and green when it is.

One big downfall to the base is the weight of it; the base itself weighs 15 lbs.  The seat is also heavy at 10 lbs, but the soft handle and narrowness of the seat helps with easier carrying.


Overall impressions
Overall this seat is very well suited for larger/older babies.  The rotating hub is a nice feature, especially if you don’t always take the seat out of the car with the infant in it.  Due to its decently tall shell, the seat is a long-lasting rear facing only seat.  The upholstery is soft and easy to clean. A few of the downfalls are the newborn fit and the weight of the seat.  Due to the hub on the bottom of the car seat, it can also make it a bit awkward to carry.  We typically kept it in the car most of the time and just took her out.  If we were going to be out for a while, we used the stroller frame with it and that was a nice addition and much easier to deal with than lugging the heavy seat around.

Orbit G3The Orbit Baby G2 rear facing only seat has been replaced by the G3 with a few changes to the look and feel of the upholstery.  They have the same specs though. You can find the Orbit Baby G3 on

Orbit Baby didn’t endorse or provide the seat for this review.  As always, opinions are all our own.

The Four Steps of Car Seat Safety


Rear Facing

Rear Facing Infant Seat

Rear Facing Convertible Seat








Rear facing is the best protection for a child’s developing spine. Rear face to a minimum of age 2, ideally age 4.

  • Position harness straps at or below child’s shoulders.
  • Position chest clip at armpit level
  • Seat is installed at the correct angle
  • If using an infant seat, ensure handle is locked in a travel position per the manual.
  • Child is within the weight and height limits and has 1″ (unless otherwise specified) of shell above their head.
  • Rear face to the limits! Don’t worry about the child’s legs, they are safe and comfortable with legs crossed, propped up, or hanging to the side.
Forward facing

Forward Facing


When a child has outgrown their rear facing convertible (not infant!) seat and is at least 2 years old, move to a forward facing seat with a 5 point harness.

  • Straps are at or above shoulders
  • Chest clip is at armpit level
  • Ears are below the top of the shell
  • Top tether is attached





Belt Positioning Booster

Backless BoosterWhen a child has outgrown their five point harness, is at least 5 years old and is mature enough to sit properly, move to a belt positioning booster.

  • High Back BoosterShoulder belt fits evenly across and flush with the torso, not cutting into the neck, slipping off the shoulder, or held out in front of the chest.
  • Lap belt sits low on the hips, touching the tops of the thighs.
  • Child is mature enough to stay seated without leaning out of the seat belt or unbuckling for the entire ride, even while asleep.
  • Shoulder belt threaded through the guide and positioned at or above the child’s shoulders.
  • When using a backless booster, the child should have head support from a vehicle headrest at least to the tips of their ears.
  • When the child is not in the vehicle, always secure the booster using a seat belt (or lower anchors, if provided) to keep it from becoming a projectile.


Seat Belt Alone

When a child is at least 10 years old and can pass the 5-step test, they are ready for an adult seat belt alone.

Seat Belt

  • Child sits all the way back in the vehicle seat with knees bent at the edge.
  • Shoulder belt fits evenly across the torso, not cutting into the neck or face.
  • Lap belt is low on the hips, touching the tops of the thighs.
  • Feet are on the floor.
  • Child can stay seated comfortably this way for the entire ride.


A chest clip goes… on the chest!

chest clip, retainer clip, armpit, best practice, Safety 1st, Guide 65

Proper Chest Clip Placement


Or more precisely, in the middle of the sternum. The retainer clip is designed to keep the straps parallel over the torso in a crash. Too low and the child could be ejected from the seat in a crash; too high and the child could suffer a neck injury. Line it up with the top of the child’s armpits, and it’ll be just right every time!
