Every Minute....yukky, didnt realise how much that woman vomited during her labour ! Why are some women sick like this ?? I know some of them may poo a little, but actually vomiting ? Are they ill ?
It's the pain, and getting rid of bodily stuff you don't need, to leave your body free to do what it needs to do. Same if you have a heart attack - people often vomit and poo, to get rid of stuff you don't need at that minute.
Most likely sick due to nerves and it was meconium she passed ( Baby pooing whilst still in the womb ) she wanted a pool birth but couldnt becase of baby passing meconium which can be dangerous
