and some kids have one mom and no dad or one dad and no mom. every family is different! but so what? people are people.

and you know what, I don't think the idea of two moms or two dads is weird to kids, until they are told otherwise. I remember when I was little, I used to wonder when two women got married, did they both wear wedding dresses? it never occurred to me, until I learned otherwise, that it wasn't "normal" for two women to get married.
