Are Playdates Really for Babies?

We had 8 other mommies and beyond adorable babies (from 3 months to 14 months old) over today for a playdate, and it was so much fun.  I wish I would have got pictures of everyone.  I had such a great time watching the kids play and chatting with the other moms that I started wondering, "are playdates really for the babies?"  I swear getting together with these girls helps me stay sane.  Luckily, Thursday night is mom's night out so my sanity will *really* be in check this week! ;)
