Daycare in FG/CH

You can see if there is a Ft. Greene parent group on yahoo. You might want to join the Prospect Heights parents group (on Yahoo) since there are usually posts by parents looking to help their sitter get a new job or I have noticed quite a few people looking to share a sitter with another family, etc.
If you go to the home page of your local community board website they have a link for schools and daycare centers. Good luck

There's a day care center on Fulton and Irving place. We don't have any kids and haven't looked into it, but it's a fairly large establishment.

I babysit, but I am thinking I should do a daycare with all the new kids coming around.

I hope you find some place suitable. There are yahoo groups that might be a great place to ask.
