ROT isn't a bad place to begin labor...really! A few good contractions usually are all that are needed to encourage the baby to find a new *better* location for birth. I'm not trying to minimize the pain of a poorly positioned baby in labor, but I am horrified at the amount of guilt and energy poured into prenatal positioning. Your baby is 1/8 turn from ROA. Most babies in ROA still turn to occiput anterior for the trek down the birth canal. LOA, is just 3/8 turn from ROT. And baby would have to pass the optimal OA to get there!
But, since you're worried and want a position...
To rotate the head of any baby: Any position that puts the baby out of the pelvis, like extreme side lying or knee chest, + makes it so the baby's back is up is what you want. So, side lie (that's on your side, one knee bent up to your waist, that knee on a pillow, a pillow behing the small of your back and flop over towards your knee, face into the bed-ish). Your baby's back is on the Right, so lay with your right side up. The baby's back might fall to the gravity side, the left. Avoid deep squats and big stair steps until the baby's turned to your preferred position. Hopefully that's a comfortable position for you, so you can combine this with resting.
