We have 17 new two-year olds in the school and have been phasing them in at a rate of two per week since the beginning of August. I don't know whether the separation is harder for the children...Or for their parents. Coming to visit for short "play dates" prior to enrollment -- something we encourage of the incoming families -- makes a HUGE difference in acclimating them once they actual begin "officially .". Things are off to a great start!
