The only thing that really jumped out at me about your post is that you seem very sure that your DS isn't ready for preschool. On one hand, you could look at this as being a very aware and supportive parent... but you also want to be careful not to convince your DS that he's not ready! I've found that my son is very perceptive and tends to live up to my expectations. If I expect him to act out at a group function, for example, he probably will... possibly the downside of being connected and attached to one's children?

Oh, and I should add that my son started 2 days/wk in preschool this summer, and he loves it (even though I wasn't crazy about the idea at first). I kept telling myself, "But I didn't go to pre-k, and I was fine!" Then one day I realized that back in the 80s, lots of people were home with their kids... I always had lots of playmates around. These days, we're lucky if we see one other child for DS to play with when we go to a playground-- and families are always so busy!! DS has had some "incidents" at school that have made me question my decision to send him to pre-k, but he's always excited to go back, which makes me realize that even though I'm not the biggest supporter of pre-k, DS definitely is.
