Rowan and I were talking about air and then how fish breathe...
Rowan: Whales have a blow hole in the top of their head.
Me: That's right because they are mammals like us and breathe air.
Rowan: But you are not a mammal daddy.
Me: What!? Yes I am.
Rowan: No you’re not, because you don't get babies in your belly.
Me: Oh right...only girl mammals get babies in their bellies.
Rowan: But did you know that sea horse Daddies get babies in their bellies?.. I like sea horses.
