WHY DOES BEYONCE KEEP POSTING PICS SHOWING THE BACK OF BLUE IVY'S HEAD?

Beyonce posted these pics on her Tumblr page over the Thanksgiving holiday. She keeps posting pictures showing the back of  Blue Ivy's head. Why na? You either want to show your baby or you don't but posting all these pics of the back of your baby's head is just ridiculous. I don tire for the suspense.
