2 and 4 yr old brothers w/ RAD- Help! Vent and Questions...

No, there has not been a RAD diagnosis. Their current foster mom said that she sees symptoms of RAD in the 4-year old. I am thankful that there were foster parents to take these boys when they needed a home. I just wish I could have gotten them sooner so as to lessen the amounts of transitions they have had to go through. c.a., thank you for all the book suggestions. I will definitely look them up.
