Where do babies come from???

After Sue and Jeff were here (and Sue is 6 months pregnant) the girls were asking me about her belly. I explained that's where babies grow until they are born. Brief and to the point, I hoped! They said Betsy (mom from daycare) had a baby in her tummy. I said yes and I had BOTH of you in my tummy. Taylor looked at me and said, "I think I should have been in dad's tummy and Allie in yours." I really am dreading these questions...at least for now brief answers do suffice!!
