a wave goodbye

So today, when i dropped Hudson off at daycare and went to leave, he looked at me - waved goodbye - and went on playing. This may seem normal to some people, but in the 17 months this child has been at daycare he has NEVER been ok with me leaving. He's always put up a fight, a cry, or tried to follow me out the door. But not today. Today, he was ok with me being gone...my little independent man. Growing up too fast...
