We just moved to a new area and are trying to figure out preschool options for our 3 year old. He really thrived at his previous school and so it seems obvious that we need to enroll him somewhere. I'm just really uncertain about our options and how much I should really be worried about it ( both cost and location/convenience are issues). On one hand, any place will get him interaction with other kids, group activities and some structure. On the other hand, his teacher will probably be the most influential adult other than us, at this point in time. I want to be nonchalant about it, like he's only three, but on the other hand I feel like so much of one's personality is determined under the age of five. Thoughts?
