My grandson puts himself to sleep by pulling on a sock with his mouth to start to untangle it until all of the threds are pulled out. What can I do to change this behavior.

Also, my 13-year-old grandson is home schooled and has no friends other than family and his puppy. Is there any kind of social activities he and others can attend? Are there any churches who may have Youth Meetings where kids can meet and greet, maybe dance and sing or play card and board games>
