I didn't mean to say that she will develop preeclampsia but just to be aware of its symptoms and watch for it. I spilled protein all three of my pregnancies and didn't ever get toxemia. But in some cases I have seen it develop in pregnancies in the 20-24 week mark so be watchful.
Good luck to your daughter. I am happy she is going to try the natural birth. It is disenheartening to see epidural rates as high as 95% in some hospitals.
