All preteens and teens wonder whether they’re normal. Clearly explaining what physical changes to expect will reassure your daughter that she is developing as she should. The order of the changes below reflects the pattern most girls follow, but changes may also occur in a slightly different sequence without any cause for concern.
• Breast development. Breast development starts with breast “buds,” small mounds beneath the nipple and areola, the dark area surrounding the nipple. As development progresses, breasts grow rounder and fuller. The nipple and areola also darken. A girl’s breasts often develop unevenly, especially at first. If this unevenness worries your daughter, you can point out that most women have one breast that is slightly larger than the other, but that the initial size difference usually decreases over time.
• Pubic hair. At first your daughter may notice just a few fine strands. Pubic hair becomes characteristically coarse and curly late in puberty.
• Growth spurt. By age 15, your daughter should have experienced a stage of significantly greater growth-in height and weight. If not, consult your family doctor.
• Vaginal discharge. During puberty, your daughter may be concerned when she first notices a yellow or white stain in the crotch of her panties. You can reassure her that this is a normal fluid that cleanses and moistens the vagina. There’s nothing to worry about unless she experiences vaginal itching, odor, or irritation, symptoms that could indicate infection. This discharge is usually a sign that a first period can be expected in about a year.
• Underarm hair. This is typically a development of late puberty. In fact, many girls don’t grow underarm hair until after they begin menstruating.
• Menstruation. Most girls get their first periods between the ages of 12 and 13. But everyone’s clock is different, and it is normal to menstruate as early as age 9. Some girls are late starters but most reach puberty by the time they’re 16. Consult your family doctor if she hasn’t gotten her period by then.
Along with all the other developments of puberty, your daughter’s sweat glands will become more active, and perspiration odor may be the noticeable result. This is a good time to go shopping for deodorant. At the same time, more active hormones and oil glands may lead to the first breakouts, particularly on the face and back. You might add medicated acne-fighting lotion to the shopping list. Let her know that bathing or showering, washing the hair regularly, and keeping the face and hands clean are essential. While you’re on the subject, make sure your daughter understands the importance of personal hygiene. Since the urinary opening, vaginal opening, and anus are close together, girls must remember to wipe themselves from the front to the back, to avoid spreading bacteria.
