Hi H.,
Well all we moms feel your sleepless pain! But here's the deal. If your baby can roll over, she has enough strength to pick up her head when she rolls over onto her tummy. That's why the stats show the rate of SIDS drops drastically after they are able to roll over. Does she take a pacifier or suck her thumb? If she does, I would just leave her on her tummy and give her the paci/thumb. If she doesn't do the paci or thumb thing, I would still leave her on her tummy and comfort her with some pats to her back or her buns and soothing words and then let her cry if she needs to. Don't pick her up because then she'll never learn to self-soothe. Also, and this sounds really retarded, but we use a hair dryer for white noise and it works like a charm. I use it to put my baby to sleep and if she wakes up for some reason during the night, I turn it on then, too. I have one with the fan/low/high heat options so I can leave it on fan instead of having the heat on sucking up extra energy. So good luck and God bless. And remember, like so many mamas have said...this too shall pass! Enjoy mommyhood! It is the best, most rewarding job on earth!
