Re: 4 y old get out of car seat
I had the same exact problem with my 3 year old daughter. The way we coped was by providing her distracting things to do. We gave her crayons and paper to color, books to read, her own little cd player to listen too, dolls, all kinds of things to keep her occupied during car trips. If she undid her buckles anyways, which she sometimes did and still (rarely) does, we have turned the car around and gone home. We explained to her why it was important to stay buckled and that everytime she unbuckled herself we we're going to cut the trip short and go right home. Be consistent and follow through and she should stop.
