Actually Mamacat....
As a result of being a preemie (10 weeks early - only 2 lbs, 14 oz at birth) he went from being a VERY verbal toddler to developing a stutter whe nhe entered pre-school. He had a year of speech therapy and when he started 1st grade this year it was nearly totally gone. There is still a pause now and then when he is tired but he is fluent.
During the brief period of stuttering he did get very frustrated. He knew what he wanted to say and how to say it but he just couldn't get his brain and mouth to interact. He would pound his hands on the floor or desk in frustration when he couldn't get things out. Even though he is now fluent I think he still may hold some of that frustration or embarassment of his past problems inside and that may hold him back when he meets new kids or when kids think he is wierd.
He is now very verbal again especially with adults but adults are more accepting and understanding than kids can be so he may have a greater comfort level with them. I'm not a psychologist or anything but these are my feelings and observations. We talk about everything, we're buddies and I do try to feel him out when I sense that he's feeling upset.
He's a great kid and I have every faith that he'll turn out okay, I just dont want the school to put labels on him that may effect him later and as I mentioned before, I dont want to trivialize a real potential problem if it exists.
Thanks for your help again everyone....the comments help as does having an uninvolved person to talk with about it.
