Pretty much what I was thinking. There are so many things relating to children that people use as arguments against polyamory, that occur in monogamous relationships too.
There are divorces, step-families, boyfriends and girlfriends of your parents, etc, in tons of families nowadays. Pretty much every time someone says "but polyamory is wrong because what would happen in this scenario involving parenting?" there are examples of these cases happening right now in mono families.
You don't even need to look at divorced and remarried families (or single parents) for that. These things often happen with friends of the family, too. Are parents not supposed to have friends in case they have a fallout and the children miss their buddy?
