Pro's: It is on the school site. The kids can just walk right over. The summer field trips are fun for the kids.
Cons: Tiny daycare for the age group and amount of kids it caters to. The teachers don't seem to really care about the kids. The teachers yell a lot. It smells awful. My kids brought home fleas on at least 2 occasions. And they repeatedly let a child with head lice return before their head was cleared.
So, the daycare was good for being close to school. But that is About it. When I had my baby I decided to keep the kids home with me while I was in maternity leave. And they never went back. I'm glad I made that decision.
