My 10mo daughter doesn't go in the car seat in my husbands car very often (she's usually in my car), but today I was driving his car with her and I could hear her pressing the button to undo her seatbelt! I started talking to her and passed her a toy to distract her but she did it the whole way home. I don't think she has the strength to undo it but I'm scared she might get it undone without me noticing! Any idea what I can do? Would wrapping a hand towel or something around it after she's buckled in potentially affect the safety of the seat in a crash?
