DS8 always have to make some sort of noises while he is working. He will either hum songs/ music, sniff (almost non-stop), or clear his throat.I believe his behaviour is quite disruptive to the other kids in class. Over the years, his teachers have been very patient. Last year, the teacher used subtle methods by reminding him not to sniff by either pointing to her nose, or asking him if he needed to clear his nose. This year, he has started humming his favourite classical tunes. I have read that there are nothing much that we can do as asking them to stop will only increase the frequency....but sometimes I can't help it! What can I do at home? Should I let him be (which is mostly what I do now as I thought that home should be a relaxing and comfortable place), or should I do something else? I do remind him now and then that he has to be considerate about other kids in class.. but I think, most of the time, he just does it sub-consciously.
