At 16 weeks Curly has mastered the skill of rolling from his back to his belly. View exhibit A:
Rolling from the belly to the back, which is supposed to come first developmentally, doesn’t come as easily and he gets mightily PISSED OFF. This has made for some interesting times in the crib at night so this weekend has been dubbed “Tummy Time Boot Camp”, wherein we will place him on his tummy all day to try and improve his belly to back rolling skills.
Oh and that title up there? It refers to exhibit B:

My towel!
We had hung his damp bath towel over the end of the crib to dry and when we checked on him a few minutes later, that’s what we found. When your baby begins to roll around on his own, don’t hang things on the side of the crib. Lesson learned, Curly, lesson learned.
