babies can flip at any time but they can also flip back.
That's nothing to be worried about. Babies are often moving around constantly, but it isn't rare for them to be in the same positions for various ultrasounds
Being head down isn't a sign of an early delivery. It's just a position. Actually, as time goes on with a pregnancy
, it is very common for the baby to go into the head down position and stay there...it's just kind of how they are programmed to do things.
