The past few weeks I've been working on animal sounds with Austin. We have started with the cow. When I'm changing his diaper in the mornings, I say, "Austin what does the cow say? Mooooooooo". He smiles and purses his lips together real tight and says "mmmmmmmbaaaaaaaaaa". I laugh everytime and now he does too! He tries so hard and you think he's actually going to do it and he follows it up with 'baaaaa'.
