We talk*! And eat our feet! (Multitasking, man...)
We roll over! And rage about it! (It was a fine idea at the time...)
And now we roll over in the middle of the night and sleep on our belly until morning. Which a few months ago would have scared the bejeezus out of me, but he's pretty mobile with the head and arms now, so I'm much less worried. I mean, I still go in and check on him several times per night, but there are no panic attacks over it. It's also translated into him sleeping a longer stretch after his 3AM feeding, so he essentially skips his usual 6AM feeding and pushes it back to an 8AM feeding (I used to do both before taking him to school). Yay for more sleep, for everyone!
* Sounds a lot like "da-da" although he's addressing his feet, so who knows....
