I'm looking for suggestions for part-time preschools in the area that will take a kiddo who's not potty-trained. My three year old son is a funny, happy kid who's interested in others but we've always had in-home care for him. I want him to get some socialization and start to be ready for kindergarten... and hopefully pick up on using the toilet! Any reasonably-priced suggestions in the area? I can't do coop because I work and have an infant, but something for a few hours a day a few days a week would be great (Montessori would be a plus).
