Hi, my beautiful DS age 5 makes noises with his mouth and throat when he is tired,( clicking and quiet grunting ). I took him to doc as I know it is very common at this age especially with boys to make random noises. Doc said best to ignore as goes away. It did over a year ago but has made a return, especially when he is tired. I am really just looking for any other experiences of same and maybe an idea of how long it went on for. I am only concerned as he says he has to do it, I tend to ignore it as per docs advice.
