I haven't done a thing. I walk a lot at work, but I think the doctor shook her down a little bit last week. After he jiggled my belly, she turned her back out and after a few days of cramps and back pain, I woke up this morning feeling pretty awesome! I can fit my entire had between my bump and my ribs now, whereas before, she was ontop of my ribs. Ouch!
I still have a bit of back and hip pain, but there's still about 10 pounds of baby, uterus, and fluid in there, so I'm pretty ok with being a little achy.
