I got to hold Grayson's baby sister for about an hour, until she fell asleep. It was great. The best part was being able to hand her off to someone else when my arm also started to fall asleep.
Grayson's birthday is exactly a month before Alice's, so every year his party marks the beginning of preparations for Alice's birthday and a reminder that she too is about to be a year older. Something about turning 5 seems like a big milestone.
