Have you looked into sensory integration disorder? You mention several things consistent with that. My son has sensory and I am happy to offer information about that. good luck
Hi and welcome and sorry what your going through. You son needs a professional evaluation by a child psycholigist. If you already took him to one and they say that this is normal, you might want to try a second opinion. All children relate to other children differently but the biting to me seems a bit out of the ordinary also his inability to stay focused. Also have him see a regular child doctor about his pooping in his pants.
Agree with the above. Definitely has symptoms of ADHD, so I would start with that.
I'm curious as to why they said that he does not have autism. Speech delays, along with the other symptoms, are a pretty good indication of autism. The good thing is if you get a diagnosis (ADHD and/or autism) he would start getting intervention at school. Instead of just punishments they would find ways to work with him. It does sound like he has a developmental problem and if that is the case punishing alone won't help since he cannot just choose to stop his behavior. A developmental pediatrician's advice seems necessary. .
hi all thanks for your point of view and the tips , yes i don't think is normal after he did the autism assessment and it came back negative they said it maybe ADHD but they cant evaluate him as he is too young, I got in contact with 2 psychologists for next week in order to get a evaluation and as well have a big meeting in the school, i am afraid that all the punishment he is getting at school and at home is just making it all worst and i wanna find a way for him to go true it and learn his full, he is not a bad kid he is very loving but for me seems that he just can't control what he does .
