I follow a blog called "And Babies Make Four", it is a blog written by a mother of twins who were adopted at the same time as Mimi and they are from the same orphanage.
I have been following her very creative and amazing blog since our girls were babies and she just posted a link to a documentary that follows the life of four adopted Chinese teenage girls over a three year span. The filmmaker is also an adoptive parent.
I am very anxious to see it.
