So, Adelyn had her first 'coo' this weekend. She has no idea how she does it or even where it comes from. Mommy knows this because as soon as it happens her forehead wrinkles up and she looks perplexed! She also had what might be her first smile... at first I thought she realized what a great sense of humor her mommy had, but then I smelt a little gas. So my question is does this date go in the baby book as her first smile? I know boys think toots are funny, but do girls?
