Yes. That was DS4. Fighting all the way. I just figured he was trying to poop and flopped over along the way! :p
DS7 rolled in a way that seemed more accidental...or easy...or something. But he did it more often. It didn't seem like he could control it, but it also didn't seem like he was trying to do something else and accidentally rolled over. It seemed like he just suddenly found himself rolling over. It was odd.
DH yelled at me for putting the baby down on his stomach for a nap once--SIDS being our greatest fear at the time, of course. But I KNEW I put him down on his back. I pointed to the kicked-all-over blanket and DH agreed that it looked like DS must have rolled over. Then DS did it a couple of times while I watched him. It freaked me out!
This was also the kid who got mad and literally threw his pacifier across the room at a few months old! (3mos, maybe? Less than that? He was nowhere near sitting up yet, I know that for sure.) We got the hint and never gave him a pacifier after that, obviously. But that was pretty freaky, too!
