My daughter was invited to a birthday party in the park on Sunday for a 2-year-old girl. We have a nanny share with another family. Our nanny has a friend who nannies in the neighborhood (also a share) and all 4 of the kiddies hang out almost daily when they go outside to play. I've never met the families or kids but I am excited to meet them.

I don't want to spend too much money and I need to go pick something up tomorrow. I have no idea what she likes. Any suggestions?
