My baby's growing up! :(

I just went to change Jaina's clothes... her legs are too long for her 0-3 month clothes! Just when they fit her perfectly everywhere else, her little long legs are too long! Her feet have been just *almost* too big for the sleepers for about a week. So now my 7 week old child is in 3-6 month clothes. Oh, well. I guess that's normal. At least we know she's a healthy baby!
