Well, kids with ADHD have 4 times more wetting accidents then kids without ADHD - so there might be some connection. But, this is something that would typically be going on since they were much younger. If this just recently started, then something else is going on.
Usually, at this age, I blame the situations with school bathrooms and teachers bathroom policies. However, I would think he now is not in school? Where and when is this happening?
no its not a sine of ADHD
it could be a sine of an anxiety disorder and him pooping himself is his reaction when he is overly anxious or it could be Childhood disintegrative disorder if he is losing some of his basic skills it could be Childhood disintegrative disorder
