my 7 year daughter sweat having odour ..is sign of puberty?

A. Hello good evening !! Sweat excretion depends on body type ,few body types sweat more and have bad odour . But bad odour due to sweat observing in recent times might be a sign of puberty,hormonal changes and due to hair growth also cause sweat,bad odour. Give more water and fluids ,avoid dark colour heavy ,silk clothes . Cotton clothes are best as they absorb sweat well.
