Today D and I were having a conversation about mommies and daddies and how they become mommies and daddies in the animal world. He told me that in seahorses the daddy makes the baby not the mommy. So then I said shouldn't he be called the mommy. The poor kid. I think I confused him. Hopefully he didn't think I was serious.
Although, I guess that would be the case if the title Mommy was only attached to the person carrying the baby and not the gender.
