Where Do Babies Come From . . . Almost

So, I'm sitting with Kadin and I notice that he is staring at my chest. Now, I'm not really sure what he's looking at, so I don't say anything . . . until . . .

Kadin: Mommy, what are those big things? (Yes, he did say BIG things)
Me: What are you talking about?
Kadin: Those things. (as he points to my chest)
Me: Those are mommy's breasts.
Kadin: Do I have bests?
Me: Umm . . . well you do, but they are different than mommy's.
Kadin: Why?
Me: Well, mommies use their breasts to feed their babies.
Kadin: Like Bella when she was in your tummy?
Me: No, babies only eat from their mommies when they come out of the tummy.
Kadin: So, Bella was in your tummy, was I in Daddy's tummy?
Me: No buddy. Remember when I told you that girls and boys have different parts? Well only girls can have babies in their tummies.
Kadin: Did Bella eat your big things?
Me: Oh, look I think I see Daddy!
