My son is 39 months old. He has been seen by our local Regional Center to be evaluated for hand flapping. Long story short..he was dismissed at 3 after speech therapy (for eye contact) and OT. They say he is progressing fine. He is in preschool, does great. Very social, great at imaginative play. The only red flag I have ever had with him is hand flapping. He has flapped since he was very young, like 6 months when watching a ceiling fan. It has now evolved into hand flapping, staring, facial grimacing and jumping all at the same time. It is only for a few seconds and it almost seems involuntary at times. I can stop him at any time by touch or talking to him. It is as if his whole body is affected. This happens when he puts something on the table and it is in his line of sight. It may happen ten times a day, or not at all. It seems to happen more when he progresses in another area such as speech. He likes to watch wheels of a car or fan but again, it is just for seconds and then he moves on. Our MD doesn't seem very concerned nor did the therapists he has seen. The preschool doesn't notice it much because when he is engaged in something it doesn't happen as often. Only when something really excites him. I have read all the autism, Aspergers stuff and it just doesn't fit. Same with the information in Out of Snyc child. He is smart, great verbally, uses sentences, doesn't fuss at routine changes etc. Are all children who flap considered autistic or PPD? Can a "normal" child exibit these behaviors?
