Hi Jillio,
Thanks for sharing that with us. If your point is that CI children still need to be supported with their peer relationships, expressive language etc then I would agree with you.
You may also be interested in a research article by Yael Bat Sheva published in 2001, which looks in detail at the peer relationships of those with CIs. She did find that relationships improved with other hearing children but of course it still wasn't perfect and they still faced obstacles. You can read the full text here -:
