This one almost looks choreographed, as they look like they are moving in unison. Simon had been asleep for a while, so wasn't bothered by all the hubbub.
I love this one--it looks like they are holding hands. Sweet. My theory is that Will was trying to wake Simon so that they could find out how to get out of that crib, as he was not too happy about this photo shoot. It will be fun to watch these two cuties grow up together. What memories will be made! : )
