We have read that the baby can now hear and recognize voices. It can especially hear women's voices due to the higher pitch. Since the poor little bugger gets to hear me yammering on all day, we make sure Adam talks to the baby a few times a day.
Before we go to sleep at night, he usually puts his mouth near my stomach and says a few general things to the baby. The other night, he was saying more and I couldn't hear him. I said to him, "What are you saying?" He turns his head without moving and says to me in a completely deadpan voice, "I wasn't talking to you." And then turns his head back to finish his "conversation." Totally cracked me up.
