This is driving me crazy, Luke has figured out how to get his arms out of his car seat straps. We tighten them to the maximum but he still manages to wriggle enough to free one, then the other comes out easy. We have a recaro young sport in one car and a maxi cosi pearl in the other and he does it in both. We end up having to keep pulling over on every journey and it's so dangerous. Am I being really dumb and missing something?! Like I said, the straps are adjusted to as tight as they can go. He is very tall, same height as a 2 1/2 year old. Has anyone else found this problem? X
