My grandson is 8 years old and is in constant trouble in school. He is very small for his age but smart. His grades are good, but he can't/won't stop talking and disrupting the class. The teacher is considering holding him back because of this behavior. She feels that, while he is academically prepared to move on, socially he is not. His parents have punished him by taking away privileges (video, TV, computer, etc.) He always feel badly about it, but, it continues. Any suggestions?
