For weeks he has lain on that playmat making no attempt to turn whatsoever, just grinning gummily at me whenever I nudge him and say fondly, 'Move it, you lazy lump.'
Then today, just like that, he rolled over cleanly, popped up his head and pulled his arm out from under him as if he'd been doing it all along. It was so quick that I missed most of it. I put him down on the mat, turned to say something to Moppet who was hopping around behind me, and turned back just in time to see his surprised little face popping up off the mat.
Since that first roll a few hours ago, it appears he has sprouted springs on his back. Lay him down and boinggg!, he's on his tummy in a flash.
So he's been doing that all morning, and then another surprise. I left him on his mat for about 10 minutes as I went to deal with Moppet's home from school routine, and came back to find him curled up on his side, thumb in mouth, fast asleep! First time he's ever put himself to sleep with neither boob nor rocker to help him nod off. It must have been all the rolling around.
And as I write this, he's off to la-la land by himself again, after an energetic half hour of post lunch rolling over.
It feels like he was just patiently waiting for the right time, so that he could do it correctly and with minimal effort. If I were a more mature adult, I'd admit that that's a far more sensible outlook to life than my own energy intensive try-to-do-everything-all-together one.
But I'm not, so I won't.
I may just follow his example and take a nap though. Baby steps, see? :-)
