My ds is 8 and bizarrely has BO. He's a very active child who rarely sits still, and I've noticed in the past month or so that when he walks past me there is a very definite smell of BO. My other son who is 11 doesn't smell at all.
Yesterday I went into his room just after he'd got changed out of his school uniform and the whole room smelled!
He showers thoroughly every second night, I guess I could increase that to every night (gulp) but does this seem normal? Obviously I don't want to give him deodorant at this age, can't be good surely, and even my 11 year old doesn't need it yet.
My dd, 8yo, has started with whiffy armpits in the last year. Like your ds, she is very active, after dancing class she sometimes smells quite strong. I haven't resorted to deoderant yet, so would be interested to see replies wrt that. However, she bathes every night and has a good wash each morning, so it's not really a problem. I would say nightly showers are essential, that should be your first priority, rather than masking the smell with deoderant.
His clothes are always clean (honest!!) and I've noticed even if he showers one night, by the end of the following day he can sometimes be a bit whiffy.
I know it sounds lame, but it's such an effort to even get the two of them to shower every SECOND night!! The idea of doing it every night.....am soo lazy obviously! However, I guess I'd rather do that than give him deodorant. He's totally unaware of the smell any way, don't want to give him a complex.
