This is my first post so forgive me for not knowing as much as others. I have a 4 year old son who is having trouble with preschool and I have having a hard time with him. He has been removed from two daycare/preschool centers for being overly agressive and that's more or less where the trouble started. Here's a little background on my DS. He's an only child, I am a single mother his father is in the military but over all isn't involved in my sons life. My DS is very close to myself and his nana. He has trouble with loud buzzing noises and he cries for hours knowing he's going to get a haircut. He's still mouthing objects and is very impulsive he has poor eye concact and needs to be in your face at all times his spech is beyond that of a typical 4 year old. He's very smart but can not sit still. His hearing is perfect as well as his sight. He isn't aggressive unless provoked but sometimes finds humor in others pain. He has not hurt anyone or any animals and I don't think he will ever be a threat to him self or others. He's a very sweet boy. When he aks question he has to ask about 5 or 6 different ways, I'm not sure if he doesn't understand or wants to make sure he is getting the right answer. For example he will ask mommy can I have your juice me:yes you can him: so I can have it me: yes him: your going to share your juice with me me: yes him: its all mine me yes him: no one elses me: yes its yours him: so this is my juice me yes DS its yours him: I can have your juice... and it will go on like that until I tell him in a loud voice its his. And its not just juice it anything... he is also very very clingy he can't go to sleep unless he has a death grip on my arm or is touching me in some way. He doesn't like to brush his teeth or hair. Can't seem to understand if you spill something clean it up. He loves baths and to be nude. Doesn't dislike clothes but is usually in his undies most of the time (at home) no matter what the season, but always wants to be under a blanket. I know most of you aren't doctors but I'm lost I took him to see a psychiatrist and we tried ritalin that was a disaster he's on a waiting list to see a developmental pediatrician he's seen a neurlogist and we are waiting on a mri to rule out a teploral lobe tumor (he has history or begin tumors) i have to tell him the same thing over and over to get him to listen. Ive tried taking away stuff (toys and such) ive tried behavior charts, time out, redirection the only thing that seems to work is yelling and having to firmly grab him and force him to look at me i'll be 2 inches from his face and tell him to stop or what not... i HATE doing that i feel its mean and he's only listening because hes scared not because he's learned from his mistakes. Im so lost. If anyone has answers or can point me in thr right direction so i can start to help him until we can see the dev pediatrician that would be great!
