Hi, my eldest had one at a similar age. It went away - when the source of the stress / anxiety leaves.
The doctor advised that:
- verbal tics go away.
- common in boys
- 7/8 is the prime age to develop it.
- not nag / tell him to stop it (as this would increase anxiety).
My son had just changed to a new school. He was experiencing bullying (but I didn't know about it at that time). He was utterly bored in class most of the time.
The ban on demanding that the verbal tic has to stop does not mean that you have to pretend that he is not making the noise. I had a very relaxed, quiet chat with him about his 'funny noise'.
He told me that to deal with the boredom at school he would get a repetitive rhythm going in his head (ignoring his teacher / other children etc) and that the noise was part of the rhythm and that it just came out sometimes.
The doctor had quietly let me know that if it doesn't stop after a year or so it develops into Tourettes. I was terrified because my son was so intense, clever & didn't really fit into the routines / sports carnivals / house points systems of school.
I was very careful not to increase his anxiety but I gently let my son know that if he had any control at all over his noise, he must stop it coming out. Because if he didn't grow out of it he would be not able to do science at uni because it would be too disturbing for the other students.
The noise stopped shortly afterwards.
FWIW my son is now 11, in high school and is having a wonderful time. No anxiety, no verbal tics.
If your son is like mine was, it means that there is something 'wrong' in his environment. For my son, year 3 and year 4 were so utterly boring. My son was stressed with having to go to school and having to fit in - having to sit on the mat and listen to the other children, having to 'learn' how to add up in columns for weeks and weeks on end.
We turned a corner when I emailed his class teacher and begged her to let my son have more interesting maths. She arranged for my E and a few other children to be pulled out into an extension class. This gave E something to look forward to as he was not bored in extension maths. One area of adjustment makes for a happier child..... the need to compensate with verbal tic left.
I hope it clears for you son.
