I was wondering this too. She started 10/24, but they were closed 1 week for Sandy and 1 week (and counting!) for roof repairs. So she's only really been there for like 4 weeks.
DD just started last week so I am doing a bottle of nail polish "for your mistle toes" and a GC to a local nail salon for a manicure. Probably spending about $22 on each teacher.
I wasn't sure what to do, but those women have really made my transition back to work so easy. They love DD and snuggle her all day. I feel really good about sending her there.
