Sometimes I think we forget that playdates aren't only for the kids.
Yesterday I had a swim playdate at my parents' house (they have a huge saltwater pool, I do not so we go there.) :-D There were 5 moms and 13 kids in the pool (it is a really big pool, I swear.) The kids were ages 9 months to 13 years old & we moms are all similar in age. ;-)
It was nice to be around other mothers and to be able to talk about decisions we were making, things that had happened and even simply laughing when one apologized for her kid being 'sassy' because a nap was not had. (I thought said kid, a 2 year old, was doing great for not having had a nap!) I also really liked that it exposed the children to other children of similar AND different ages. The bigger ones had to adjust because there were little ones in the pool and the little ones had to learn that they couldn't go everywhere the big ones did.
I'm thinking that I am going to have to plan more playdates. It will go a long way to keeping me sane. :-D
