How is it Possible?

This past weekend while setting up the new room for Andrew I was also going through his old clothes to find all of the newborn and 0-3 month size stuff for the new little guy.  In the one box I found the little fitted sleeper that Andrew came home from the hospital in. I was taken aback as just how small it is.  I mean, how is it possible that he ever fit into this:

The one on the left is the size he fits into now, although we have stopped with the footie pjs for the time being.  The one on the right is what he wore home from the hospital. And it was big on him at the time.  It seriously blows my mind that he was that small.  Especially when I look at my rambunctious little toddler tearing through our house like the crazy Tasmanian devil that he is.

What blows my mind even more is that in 4-6 weeks we are going to have another little munchkin that will hopefully fit into those little newborn clothes (yes, I would like for this kid to be about the same size as Andrew just for my ease and comfort).  It's really hitting me nowadays.  Holy cow - we're having another baby!
