Smiling or Gassy?

We're still not quite sure whether or not George is actually starting to smile. We know for a fact the kid is gassy - we should buy stock in Mylicon - but I guess we'll just let ourselves think he's smiling, regardless!
We do know for sure George is getting much stronger. He can hold his head up pretty well now. He's also starting to be more aware and see more clearly. We have an orange elephant clipped to his changing table and he's definitely taking notice, even batting at it now and then.
By the way, Brian commented it looks like he's wearing the same outfit in every photo - I can vouch for him that he actually does change his clothes, he just has a closet full of the same stuff!
