Jillio - I agree with you that implanted children need to be supported and allowed to develop peer relationships with others like them. Parents need to learn from the past and be aware that this is potentially a difficult area for deaf children where involvement and intervention may be needed. I'm not sure if BiBi is the only valid way to do this though and I'm getting the impression that BiBi programs are not very widespread. I do think that it's possible for an involved parent of a child in an oral environment to help develop their child's self esteem both at school and out of school, although I recognise that this involves commitment and a challenge. The problem in the past has been that people haven't taken self esteem very seriously or realised that it was an important issue.
I found another study with quite a large sample of children this time.
