Where babies come from

Tonight Annie said "Mommy, when you were a baby, who came to get you in China?" I said I wasn't born there, that I was born in North Bend (down on the southern Oregon coast). She said "North Bend, China?" I tried to explain the whole thing about Grandma being my mommy, but she wasn't having any of that and quickly moved on to other topics. She has gotten somewhat interesed in this whole subject lately, just as she has started asking questions about her "bio-mommy." Usually she asked one or two questions, you can see the info percolate for a minute and then she goes to something else. She will put it all together one day, but we are not going to rush her for sure.
