Another vote for Mother Goose Greendale. My 3yr old has been there since she was 11 months old and she loves it (as do we). Each room has their own dedicated outdoor space so the kids are usually out there at least once a day (frequently more often, weather permitting). They've also got a large front garden and access to the Greendale wildlife garden. The staff and management are lovely - they really care about the children. Good luck!
