My little boy is now a preschooler (well, preschool within a long daycare centre, because who in gainful employment can leave work at 2.30pm? Not me!).
He did really well today. He accepted that I would stay with him a while and that I would then be going to work. I dropped him a bit before 10 and stayed an hour, then picked him up at 3.
The staff reported that he did have a cry at lunchtime, but he was OK. I think once he settles he will love all the activities they can offer there.
Heck, he may even deign to eat one of the hot lunches too. Eventually...
