I'm having a small issue with DS. He is 20 months old, RF in an Eddie Bauer 3-in-1. He is 32" tall, 22 pounds. The seat is installed properly, and we use the pinch test for the tightness of the straps. The chest clip, each time he's buckled in, is adjusted to be at armpit level.
Well, we were on a long car trip this last weekend, and through boredom or whatever, he's figured out how to move his chest clip around. The first time I saw it way down by the other buckle when I took him out I thought I'd maybe neglected to adjust it when I put him in, so next time I put him in his seat I made sure to adjust it properly. But he still pulled it down.
Short of constantly watching him and readjusting it during a trip, is there anything I can do about this? How could I make it tighter, so he can't move it? Is there a way?
