[Fairy Tales] A man and a woman get married and have a child. However, each parent had previously promised his/her firstborn child to a different witch. What happens next?

Do the witches just fight it out? Is there some kind of witch court system that handles this kind of dispute? Will there be any consequences to the couple if it's discovered that they had set up this conflict intentionally?

I could see a few potential scenarios if it was unintentional:

* Witches brawl it out, because they both want the child for something important
* Witches have some kind of hierarchy that determines who 'gets' the kid (age, seniority, when the contract was signed, etc...)
* Magic happens and the family has twins, so each witch gets a kid

If it was intentional on the part of the couple, woe betide them at the hands of scorned witches.  Best case they have a hex put on them that they need to work off.  Worst case their lives take a dramatic turn for the worse and they die penniless, in pain, with broken hearts.
