a little belly (okay, a big one)

Well ... today I heard it about six times. "Are you having twins?" or "Are you sure there's just one in there?"

It is rather strange as I was never asked this ~ not even once ~ during my previous three pregnancies.

Anyway, my kids have heard it so much that they're starting to think it's a real possibility.

I'm either having a really big baby ... or a really big placenta??? Definitely not twins.
