My son was in an in home daycare until he was almost two, and then he moved to a small center.
I LOVE the center. They cook once a week, do arts and crafts, learn songs, listen to music, play with blocks, the sand table, dress up, in the play kitchen, read books, do science experiments, play outside...
He was starting to get bored in the in home daycare - there just wasnt as much to do. And, as they say about idle hands - he was starting to get in trouble for getting into things at the home daycare.
I was worried about putting him in a center because I thought they were big and impersonal, but this one is small, homey feeling, and family like. I really love it and all the things he gets to do there.
My daughter has been there since she was 4 months, and I love it for her too. She has had the same caregiver there for the past year, and is in a room with just two other babies. .Its a wonderful situation.
They clean all the time. At her one year appointment, her doctor commented that she had only been brought in for one sick visit, ever. Just one ear infection - my son had three or four by the time he was one, and he had been in a home daycare at that point.
