Last night Colt started making a new humming noise that sounds like he's trying to say MaMa so Danny and I mouthed MaMA, MaMa over a hundred times to him. When he woke up from his nap today he was making the same noise but a few times the sound Mama came out. Now whether he is really saying it or making noises, I can't tell. I like to think he is. :) I will try to get a video of it and let you be the judge.
