You're doing slightly better. The diaper rash is going away, but you still have poopies that worry me. Your food doesn't look as digested as it should be, but I admit my experience with baby poop is limited.

At any rate, you are a happy baby. You've been very silly lately, and love to laugh at yourself in the mirror. The interesting thing is while you are a happy baby, you are also a serious baby. I asked Daddy about this, and he said his mom used to tell him what a serious kid he was. I think you take after him in this way. You don't seem unhappy at all, just pensive. You will watch things going on around you, it's not like you're fixated on one thing (which would be a bad thing if you were). You just get this serious, thoughtful expression while you're taking it all in.

Your sitting is fabulous. And crawling is still RIGHT there. Your teeth are threatening to break too, and Grandma Laurie and I have bets on which one will pop first.
