My ex wife had preeclampsia with two of our kids. Caused our fourth child to get so stressed, he shit in the womb so much, he aspirated it. The Dr called Meconium Aspiration Syndrome. It was bad. The liquid looked like split pea soup. Not trying to sacre y'all, bit there's not much she can do so late term. Have her push lots of water and bed rest. Like, stay in bed unless it's to go to the bathroom, eat, shower, etc, until she gives birth. That's about all she can do now. And pray. Lots and lots of prayer. Hopefully the baby is ok.
