Of course, he doesn't know what he's saying. He usually says it when he's sad, because before crying he does a whiny "Mmmm, mmmm...." and then spits out a "Moommm!"
I don't actually have too many pictures of him and I, because I'm usually the one taking the pictures. But I like these two that Levi took yesterday, even though baby is making a weird face.
Love my sweet boy.
