Hi,
Sorry have filled them in for myself but not a six year old. The only advise I can offer is complete it as if it is his worse day and put down everything you have to help him do and he can't do for himself. I know it is an arduous task but keep going its well worth it if your successful. A lot of the questions are repetitive, they try to catch you out, don't worry if you find your repeating yourself provided your consistent through out you should be fine. Also put as much evidence in it as possible, letters from GP, social, physio etc.
Good luck.
