How come you're my mommy?

R asks this at least once a day and about a month ago, I figured out an answer that suited him...

"because Dr. Kim (from ESWS), Marsha (from Dillon), your Birth Mother and God said I could be."

Now that we have the answer established, when he asks, I usually turn the question back on him. He doesn't get everybody, everytime, so I help him out, but at least it satisfies him and the sweet smile on his face when he says it is priceless.
