I was wondering what to do about car seats in the USA. I still can't work out which is better, take ours, buy over there or hire. I need one for DS who will be 4.5 and one for DD who will be just over 3. I would rather take our seat for DD on the plane as she is a worm and won't sit still on the plane, she will be running around unless she is restrained. DS is not that bad and will sit but I am also thinking about them sleeping. Will our seats be able to be fitted in a hire car over there? Do all cars have an anchor point? What will be more cost effective? Too many choices, soooo confusing What did you do?
