twinmomma, great update! Sorry k3am, DD has 4 kids in her class in a 3 block radius of us and she can't stand any of them. They also only want to play at 7pm.
186momx, we have two 2nd graders, and one 1st grader within a 4 house radius, and she loves all of them, especially the 2nd grade girl two houses down. And we all seem to be on the same wave length of "playtime ends at 6:30 or if a family is having dinner." I have a love/hate relationship with it. I love when DD is playing at their houses, I love/hate having a house full of kids at mine. And they end up at our house more often than not.
DS just can't understand that the soon to be 7-8 year olds don't really want to play with a 3 year old or the fact that DD can go play at their house without a parent tagging along, but he can't.
