I love this! Didn't you love making blanket fort when you were a kid? You got your own little fun and different space and it was a whole lot easier than trying to build a tree house!
I subscribe to the Parent's Magazine daily email and even though Carson is 15, I still get some good tips every once in awhile. (it's mostly for parents of young kids) While Carson's blanket fort days may be behind him, I think YOU should stop what you're doing right now and make a super-cool blanket fort with your kid! Maybe she'll even let you come in!
