I agree with Angeliz that you may not be returning to the other thread so thought I would post my response again here.
Bafreem, so sorry that your thread has taken this turn. It is hard to get a straight answer for these types of questions but I know that you are in a quandry. Dh and I argue fairly often over what to do with ds in his schooling. At 2.6 he is on a 4 year old level in most things and I do worry about it. Do I just continue on as if he's the same as all other 2 year olds? Do I try to do extra things at the 4 year old level? Is he going to have problems integrating with children his own age? (It does seem a possibility at this point, but hard to tell at this age)
I just don't know. So, I guess I haven't really answered your question. However, what I have been doing is trying to do extra things with him to keep him challenged, while at the same time letting him continue on with age-appropriate activities and utilizing whatever opportunities we have for him to interact with other children his age.
