The South Mountain YMCA in Maplewood is another option for you. They are one of the few in the area that are open from 7 am until 7 pm and the care is wonderful. The ratio for infants is 3:1 and the caregivers stay with the class until the children are 3 years old, ensuring continuity of care. My child started there when she was 5.5 months and I've been really thrilled with the care.
I'd recommend you check out Maplewoodonline.com which is a source of local information and also has a discussion forum, similar to this but localized for the South Orange, Maplewood and West Orange. All you need to do is go to the "Latest Discussions section" and enter daycare into the search function and you will find all the threads.

Another source of great information and advice is the South Orange Maplewood Mothers and More group. They have reviews of all the daycare centers in the general area from with verbatims from mothers experiences at each. It is also a great way to meet other mothers and get their advice on pretty much anything.
