How late can a baby flip from breech?

Right up to the end.: But that isn't common. We usually will wait to try to turn the baby until around 37 weeks, as they are more likely to stay turned. As the fetus gets larger and the amniotic fluid decreases, they run out of room to turn on their own. It's happened, though.

Before delivery: Just prior to deliver, although less common than at least a few weeks prior.

Rare after 35 wks: Usually breech babies stay after 35 weeks. There are breech tilt maneuvers your OB can teach you. If at 37 weeks, you still have a breech baby, a version (ecv-external cephalic version) can be attempted. Your OB will know if you're a good candidate & good luck. I just did one this morning on a very stubborn 38 wk infant (2nd time...). Good luck with yours.

It depends: Fetuses are usually breech when they are in the 20 weeks gestation. Some remain that way and some will flip very late in the pregnancy. If you have a septum in your uterus, it is less likely that the infant will flip. An OB may try to "flip" the baby --- called a version at about 36 weeks. You might ask your OB about that procedure.
