This sudden sexual development in a child so young can be unnerving to parents. She started having body odor at 5 and breast buds at 6,” one mother wrote recently in a group chat about the condition.
The trend has been attributed to the epidemic of overweight children and a greater exposure to pollution, which does bad things to developing bodies and accelerates the timing of a girl’s first menstruation.
Environmental toxins also cause many girls to develop breasts at an earlier age than in the past.
At the turn of the 20th century, the average age for an American girl to get her period was 16 to 17.
Today, that number has plummeted to less than 13, according to data from the National Health and Nutrition Examination Survey.
