I was recently looking back at some pictures from when I was first pregnant, and what a difference from then to now! I thought I was showing at 15 weeks, and was feeling huge at about 20... look at me now... and I'm still growing. :) At my last appointment, my doctor said he was about 4 lbs., and would very likely be an average sized baby. He was already head down, and from the many, many kicks in my ribs, I think he still is!
