I really want to help Anh but have limited knowledge of CP.
What basic materials might make life easier for him and his family? People only get about $6-$9 of disability per month (if they get any) and nappies, etc aren't used as families usually can't afford them. Is there something that really helped you long term? The article didn't mention if he has a wheelchair. That is easy to get, a simple "Vietnamese style" chair is $100.
