Getting a'head' of me

I was messing around with the camera and almost by chance I took this shot.
I am have spent the past two evenings staying with M when he goes to bed until he actually falls asleep. I have spent a lot of time kissing that head, stroking that hair. I am realising at that head grows that the time I get to kiss heads and stroke hair is only getting shorter. So I suppose this photo is remind me to enjoy each moment I get to kiss and stroke those growing heads.
