Having to leave a soft existence is also a punishment, along with the curses...but I have known women that had no pain in childbirth, but that is not the norm...A friend told her husband she was going into labor and go next door to get the neighbor to assist...a few minutes later when he came back with the neighbor, she already had the baby...It was her fifth. She said she only felt a little pressure....
The curse of pain in childbirth does not always happen....just a little factoid...
I also know a woman who had little pain with half her kids. Seems to be a special blessing God gives some women.
