Since Briggs has mastered consistently rolling from his back to his stomach, in the past few days he is now rolling more and more from his stomach to his back. He's rolled himself off his blanket and play mat on several occasions. The last few mornings, I've gone in to get Briggs up to find him lying on his back, happily playing with the base of his mobile or with his feet. Of course, now he's also rolling onto his back in the night as well, so when I hear him talking in his crib at midnight...or 4...or 6, he's less likely to fall back asleep on his own because he's lying on his back.
It's so fun to see Briggs develop new skills and learn new things. Rolling is good, but I'd be okay if he started working a little harder on sleeping through the night consistently.
