Michelle;
I believe you are right about the diet. I have found that when my son eats certain things it triggers severe behavioral issues. It makes me sad for him since it's things I know he loves but I truly feel affect him adversly. He loves Cheeze its... Gold Fish... but when he has them he is completely behaviorally off with eye contact, hitting, he bit my daughter the last time he ate them.
When I remove all dairy he does terrific !!!!
He does very well talking about things that he wants to talk about. His problem comes when he is asked something he tends to flood with thought and has a hard time getting it out. He does eventually but it's alittle bit of a challenge. It is coming though !!! He also has a difficult time with the give and take of conversation. If it's not his topic then he sometimes resists and insists that it be about his interest. He's really beginning to look more Asperger like as he gets older.
He is so cute and often funny but very literal about everything and extremely rigid about how he thinks things should be. I'm always changing things so he gets used to the change and he accepts it although reluctantly.
He is extremely intelligent. He is beginning to read some and he amazingly has picked up basic math skills and although it wasn't taught to him. He picks up anything that is concrete very easily.
He also ( yaaaay !!!! ) has learned to play with my daughter and the expansion of his play has come so far. He is learning how to play with others cooperatively and does very well with the imitation.
He goes to our public school in an integrated setting for 10 hours a week. The school after a huge battle started providing 10 hours of 1:1 ABA outside of his school day. I have used some of the 1:1 time to enroll him in a private preschool with typical kids and the ABA person attends for part of that time to enhance his social skills. The private school teachers tell me he does so well that he blends with the other kids. It's not obvious unless you know what you are looking at.
Jeffrey was 4 in November. He has one more year before kindergarden. It's my hope and a goal that he be ready to attend with no additional assistance.
Most times he does very well. It seems that he's on a rollercoaster though. Whenever he is about to develop new skills, he seems to be thrown off and the PDD signs are noticable and it appears he regresses. But so far there seems to be a pattern of regression followed by a significant developmental gain and then he's great for a while.
Long winded.... sorry. Thanks for asking
