my son who has just turned 12 has started (how can i explain) clearing his throt and making a stupid sound after doin it every time! he does this about every 30 seconds and as you can amagine is doin my head in!!!!! this has been happening for nearly 3 weeks now. i thought that it might be his voice breaking but have read up on it and really dont think that this is the cause. i also thought that he might have started smoking as he has just started a new school and is hanging around with older boys who smoke.(but i have not got any evidence)... or that it is just a very annoying habbit!!!!!!!!! any suggestions would be appricated!!!!!!!
