My baby girl is growing up and changing so much. Dearest SJ, please slow down! We go for our 4 month checkup tomorrow so I will post stats sometime later. As of today...we can roll over when on our belly! I love that she is starting to get mobile but I also love that I can lay her down and she stays put for a while...which do I really want right now? She doesn't love being on her belly as evidenced in the video. She loves laying on her back and does a really good job of rolling to her side. She may start rolling over from back to belly soon as well!
