If your little one is asking questions about their Chinese birth family, I highly recommend this book. It is an emotional book to read, but it gave me a better understanding of my daughter's culture and a window into the world of the mother's that gave up their children. I purchased mine from Amazon. AC has already started asking questions. I think this is a great book to share with her as she gets older and can understand all the details of adoption. Right now she is happy with the information we have given her.
I started looking on the Internet for adoption stories and ran across this video of an adult Korean adoptee sharing her story and struggles. I cried as I watched the video. Listening to the things that she struggled with as a child and into her adulthood is heart wrenching. It shows her going back to Korea to find her family. Her adoptive parents go with her on a second trip.
There is a follow up to it you can see a clip of it here.
Also on APT tonight there is a story about an 8 year old girl adopted from China. You can learn more about it here.
