Genes from 3 babies? QW #4

There are definitely rules that should be in place when it comes to genetically making babies but I think that no matter what, it should remain 2 parents. It takes 2 people to naturally make a baby because that is how it happens. We should not be messing with more than 2 parents because things could go really wrong. Plus how would one even deal with the problem of who has custody? It is such a slippery slope that would take so much to keep it in place I just do not think that it is possible to keep a childs life healthy when they have more than one parent that not only created them, but raised them. We need to stop messing with all of these supernatural powers that are out of our control because it is more than likely that it will go wrong.
