My baby has been bottom-down (breech) for about two weeks now — I'm hoping it will turn. I've read that this is very harmful for the baby; Google is terrifying. What do you think? I'm doing exercises, I only sleep on my sides, and I feel like it's still lying the same way. I don't want to go for ultrasounds often; my gynecologist says the bottom is still down.
