I have main floor daycare. I have living room, dining room, kitchen and powder room. Toys stored on bookshelf or behind couch at end of day. Children sleep in guest room for under 2's with cribs and cots in spare room for over 2's.

Only thing maybe think about is if basement not walk out, how you get all children out if there a fire. Also, if unfinished, how will it look to potential client coming to see dayhome.
