My son is 12 years old. He is very slow in all works like writing. He couldn't change his clothes himself He is very slow to pick up all things what ever it's a game or some task given by me. Even he couldn't play with fidget spiner I gave him multipurpose tasks but he couldn't do. I'm much worried. He is the only child of mine. Although he is very good in mathematics. Sometimes he behaved like an active child. He tried much but he couldn't do. Please help. Do I need a psychiatrist?
