I've noticed that for the last week or so when my son gets sweaty he gets really bad body odour.
He's having 2 showers a day and it still only takes a bit of sweat before he smells again.
I asked in the chemist today if they had any anti perspiriant suitable for a 6yr old and they gave me a funny look and said no way.
I don't want him to get picked on because of it, it can get very strong at times.
My eldest never had this until he went through puberty so I'm completely stumped.
