Please can we have a baby girl?

The boys (well Keyton mainly) have been begging for a baby sister. They just can't get enough of these brand new babies we see. I thought it was just a phase thing, but Keyton just wont let it go. He has been asking almost everyday for over 2 weeks. So the other day I was going to get down to business with him and ask him some questions about why he wanted this baby girl so much. Here is how it went...

Me "Hey Bugs, so you really want a baby sister huh?"
K "ya, Mom."
Me "Where do babies come from?"
K "From Heaven up in the sky."
Me "Really!?! Well how do we get them to our house?"
K "Just go pick her up at the doctors."
Me "oh really?!! (thinking, wow, if it was really that easy?!)
K " yep, so lets go get one!"

First I thought how cute that he could love any baby that was waiting for us to pick up at the doctors house. One thing with kids is that they just love everyone and everything without any questions. Such sweet souls. Then after thinking longer I thought well, he is 4. So maybe I should tell him a little more about babies. He really hasn't been around anyone pregnant in our family and just hasn't asked when we see people. So this is what I proceeded to tell him...

Me "You are right, babies do come from Heaven. When they are teeny tiny they come down from Heaven and get in a Mommy's belly. (He gave me this look like, you are joking me right?) Then they stay in there until they get big enough. Then the mom goes to the doctor at the hospital and they get the baby out of her belly and then they bring the baby home."
Keyton kinda sarcastically replies "great!"

It was all I could do to not burst out laughing at his cute facial expressions trying to process everything I just told him. But you know, ever since this conversation he hasn't asked for a baby sister ;)
