Curious about booster use here. We have started to let my son ride in his maestro as a booster for relatively short trips. He is doing well, but I am concerned about this when my DH buckles him. When I buckle him I do not lock the seatbelt, when DH buckles him he pulls the belt ALLLLLLL the way out so that it locks and you can hear the ratcheting sound as it retracts. I feel like this isn't how the belt is supposed to be used with the booster but we already have so many issues with seat use and installation I wanted to check before I said something. So, basic question, is it ok to lock the belt or not?
Thanks!
Thanks!
