I’m sorry, but the parents need to start using the pronouns “them” and “their” right away. I can’t imagine a baby swathed for 9 months in artificial progesterone (or real progesterone) and coming out even slightly typical.
Good point.
I took progesterone to support my twin pregnancy. My children turned out just fine. Note tag line.
bzzzzt WRONG.
Progesterone is in the device to make the body thing it is ALREADY pregnant. That is because there is a LOT of progesterone in a pregnant womb. If you have low progesterone you lose the baby.
