Teach him to accept his stutter but also get speech therapy, to develop techniques. Although, I don't know what therapy is like for a 7 year old. You can practice things at home (if he's aware of his stuttering or is a too quiet kid), for a few minutes a day, like reading aloud and speaking in front of the family. But do not expect fluency: Just go through doing these practices. Tell him he's doing a good job. There are stutterers who can read aloud fluently because of the years of practice at home: The brain can develop new pathways, over years and years. And also he can develop some fearlessness about speaking. Don't let him clam up or isolate much: But don't pressure him to be fluent. Converse often, etc. Maybe have the entire family do these exercises. Ask the school to post info on famous people who stutter. That would help the other kids be more accepting.

Then just do the conversing and not bring any attention to his stuttering.
