Four of a Kind

This morning, a friend of mine Heather dropped off her two little boys to play. She is also pregnant, and due just a little later in the summer than me. We've decided to help each other out for our dr. appts this month. She'll be watching Jackson and Cooper next week when I go for my checkup.
Anyway, her two little boys are the exact ages as mine. Nathan, her oldest, is just a week or two younger than Jackson. Or older. I can't remember. And Austin, is just a few weeks younger than Cooper.
Soessentially, I had two sets of twins this morning. They played great together. Jackson and Nathan ran off and chatted away. The toys were spread around the house twice as fast as usual, but it was also great because they entertained each other. No one even fussed, until Heather got back, of course. Then everyone started screaming and not wanting to share, etc. I managed to get a few pictures of the silly little guys ...
