H.F.
My 8 1/2 yr old is in 3rd grade and when I go to her class I do notice that there are quite a few "odorous" kids in her class. And my daughter herself does seem to have her own issue with the matter. But it isn't my daughter's arms so much as her feet. Wholly cow, some days I think I'm just going to die when she gets in the car. Her best friend is the same way. We've bought new shoes & socks, tried odor eaters, everything... nothing helps. Her feet only stink when she goes to school, on the weekends she doesn't smell at all.
