C.,
My kids go to Country Kids in Brookfield and we absolutely LOVE IT!!! My daughter started in the preschool program and will now continue with Kindergarten there!! The teachers are AMAZING and wonderful and they teach SO MUCH! My daughter is 4.5YO and is already reading small things, adds and subtracts, etc. I totally recommend them! My son will be moving into the preschool program this fall and then he will also continue there with Kindergarten as well!
I do know that a lot of parents take their kids out for the summer....so June is a great month to try and get yours in or even call. Otherwise, I think, during the school year there is a wait list. Here is their website so you can check them out too. I also want to mention that they are not commercialized like Kindercare. This center started with 3 or 4 moms 20yrs ago and they continue to run it.
