Hi S.,
Congrats on your new part-time position! I recently made the same move. That extra time with your little one is so worth it! I remember that my son rolled over pretty early then stopped for a few months. It was almost as if he knew I wanted to write it in his baby book and then he figured he didn't need to bother with it anymore. Babies are funny and I don't think you should worry one bit about your little guy. They learn something new and then push it aside for a little while. I'm sure you'll be going for your 9 month check-up soon and the doctor can make a better assessment. -C.
