Oh Raoul... how heartbreaking. Your DS has many similar challenges to my DD and it is soooo very hard. We found a really good child psychologist (herself a 2E adult and parent to a 2E child) to work with DD and it has really helped. Also getting the supports in school is very important. I know you have posted about your difficulties having his needs met in French schools and your DW being overwhelmed by his challenges. I wish your whole family all the best. Please keep checking in here - it really does help to communicate with other parents who understand what you (and he) are going through.
