[quote]“I’m sure this isn’t the first time in history people have been talking about it. But I definitely feel like these kids are growing up faster - and I’m not sure it’s always a good thing,” says Dr. Liz Alderman, an adolescent medicine specialist at Montefiore Medical Center in New York City. She’s been in practice for 16 years and has noticed a gradual but undeniable change in attitude in that time.
She and others who study and treat children say the reasons it’s happening are both physical and social. Several published studies have found, for instance, that some tweens’ bodies are developing faster, with more girls starting menstruation in elementary school - a result doctors often attribute to improved nutrition and, in some cases, obesity. While boys are still being studied, the findings about girls have caused some endocrinologists to lower the limits of early breast development to first or second grade.[/quote]
