L.D.
I am interested in the reponses, but there aren't many so far. There are 3 pre-schools by the director of Mothers-day-out where my guy goes. It's a great curriculum, In MY OPINION.(don't know the name, but it's not Montesorri). I pay $160 a month for two 3.5hr days a week. The school goes through kindergarden. I have looked for additional days at other schools too. I ask them their teaching philosophy and then do net-research.
After you choose a philosophy you like, then see if they'll do a one month trial w/ability to drop out.
My thought; better to introduce it to your DD now before she HAS to go. Goodluck & I'll check back for the rest of the responses! :)
