I came across an idea in a blog a while back. Kids whose parents "knew" each other on blogs wrote to each other.
Ian has started writing his name, but that's about it. I think mailing a letter to a friend would be a fun weekly project. He'd get to "write" a letter, put the stamp on, and put it in the mailbox for the mailman.
Anyone interested? If you feel comfortable enough, email me. We can set up the details. One thing: I have to have had several comments from you. I want to make sure I'm not going to be giving out our address randomly.
