Thank you Lazy Bones for your reply. My daughter s a very sensiable child and one that likes to stay in every evening and concentrate on her home work etc. She is not into boys at the moment (sure it wont be long). She also likes to compete in after school sports clubs etc. Her breath is also awful in the morning and I can tell just by walking past her that she has not brushed her teeth, however she does mouth breath at night and this may be the reason why. she also complained that after P.E she felt really unwell and had to take some time out. I think, I will monitor her levels for a couple of days. If they remain steady I will not panic. Thanks
