Child seat is a good to have but not a major requirement here. Suggest you to buy here if it is too bulky. Toys... you can be selective and not to bring all of them over. I left most of the toys back home when I move here. Clothings.. plenty here ... just bring enough. To me besides your logistics, the biggest challenge here is to get your kid into a school. Can be very difficult to get into good schools and waiting list is very long.
