Meet our little model. Her parents are putting her in the Graco SnugRide 35 Click Connect that her older brother used. They made sure that it hadn’t expired, they cleaned it according to the instructions in the manual, they verified that they had replaced the buckle in the Graco recall, and they moved the straps down to the lowest slot. But now when they tighten the harness around her, there’s some slack even when they pull it as tight as it can go. What went wrong?
