If your 2 year old attended a preschool program, was it a positive experience? Would you do it again? Did you have any issues?

We're considering enrolling our daughter in a very part time 2s program this fall. Her birthday is at the end of august, so she will have just turned 2. I'm also due with our second 5 days after her birthday, so I'll also have a newborn.

My daughter is very shy, and comes to work with me, since I'm a nanny. So I think the time away from me would be good for her. The idea of a couple hours with just the baby also sounds nice. The preschool is a local co op a five minute walk from our house. The 2s program is only one day a week, for 2.5 hours.
