I'd really ask first whether it bothers the teacher (solution: get over it!) or the other kids - it's a problem only ifTHEY complain, not if the teacher think it might.
Good advice! I'd add one extra thought: with our friend the at-school hummer, no child ever took note in his first three years of school. Until one (very high-strung) teacher who couldn't stand it began to constantly demand he stop. And *then* the kids did start complaining, but only because the teacher had created an issue and they were responding to her lead.
Fast-forward three more years, and no other teacher has ever complained, and no kids have ever mentioned it again.
So I totally agree it's only an issue if the kids think it's an issue - but even if so, it's also worth making sure they haven't been primed to complain.
