Bree laughed for the first time today! I was putting her onesie back on after changing her diaper when it happened. She and I were smiling at each other and I was making faces and talking to her while getting her dressed when she started trying out a new vocalization. Kind of a quick heh heh heh. Then it turned into an obvious chuckle followed by a tiny, quiet squeal. But definitely a little laugh and an awesome indication of what is to come. I cannot wait.
Bree is rolling from her back to her tummy like a pro now. She is no longer content to stay wherever I set her down.
