Looking for a small home daycare in Willowbrook area

I'm looking for a small home daycare center, preferrably one who is only taking care of 3-4 other children, to place my 3 yr. old son in. He has had trouble in the past adjusting to the stricter daycare environment and needs someone who will be able to enforce sternly (but gently) the rules. I've found home daycare or regular daycares with a larger child to adult ratio has my son causing more trouble because the adult can't enforce the rules as well. If anyone has any suggestions that would be greatly appreciated.
