Dr. Chheda – Menstruation in girls starts at the age of 12. Now a lot of people think that might be the start of puberty. Actually menstruation is the very last thing that happens in puberty. There are things that happened before puberty including breast development, pubic hair, underarm hair and especially height. Most of the height that girls get is before menstruation. Now menstruation like I said you on average starts at around the age of 12. Four years prior to that is when the hormone starts, so eight year old girls are already having hormones. Those hormones are cycling, going through their brain, and starting that whole physical development. So when your eight year old girl starts to become a little sassy, you know it’s all hormones. And a great book that I recommend is the American Girl book called The Care and Keeping of You. There is a part 1 and a part 2, um but I recommend getting it at the age of 8 and bringing it out every couple of months, reviewing the next section so you know what to expect.
