Just for the sake of record keeping, the things that are bothering me (and that bothered my mom) are
- obsessive behaviors
- difficult to engage at times (gets so absorbed with things that he will not respond to you)
- no change in how he deals with his brother - basically ignores him, including his safety, most of the time
- discipline, talking do not help with hitting and throwing. no change in that behavior.
Again, this could all be completely normal. Normal is a broad range. But I'm going to feel better if I have him evaluated and find out.
