Preparing for Your Daughter's First Period

There's something exciting about it; periods are part of the passage from girlhood into womanhood. Yet it's a conversation that makes many parents—usually moms or female caregivers as most men don't want to touch this one with a ten-foot pole—anxious. They aren't sure when to have the conversation. They worry about scaring their daughter. And they aren't sure what information is necessary. And because periods are related to reproduction—and therefore sex—it's a conversation that makes many people uncomfortable.

Here are some tips to help, based on my experience as both a pediatrician and a parent.

When is the right time to talk?

It's hard to accurately forecast when the first period will come, but you can get clues from watching your daughter's physical development. It's getting closer when her breasts have developed to the point where she needs a bra, and when she has a reasonable amount of pubic hair, not a few wisps. Another sign of approaching menstruation is a thin whitish vaginal discharge, which she may notice on her panties. You may still have months and months after these signs appear, but it's a good idea to get your daughter prepared.

Many schools talk with students about puberty, usually during fifth grade. Personally, I think it's a good idea for parents to bring up the subject first. But some parents are so uncomfortable, they'd rather let somebody else provide the details and then just answer questions afterwards. Either way, it's a good idea to ask the school when it will be teaching about puberty. Most likely the school will let you know ahead of time, but you may not get much warning.

Sometimes you end up having the conversation earlier than you expect. With my eldest, it came very unexpectedly, when she was 10. We'd talked about where babies come from (after she and her younger brother came home from school with some very interesting misinformation they heard at recess), but we hadn't talked about periods yet. We were in a public bathroom with the daughter of a family friend. As we waited, Michaela explored the bathroom, and became fixated on the sanitary napkin and tampon dispenser. She wanted to know what they were for, and she was not going to settle for a vague explanation. So, once we were alone, I told her about periods.

What do I say?

Give her the facts. Periods are much easier to explain if, like Michaela, your daughter knows that babies grow in the uterus as opposed to being dropped off by the stork.

You don't have to get into graphic detail with children; just give them the basics with the appropriate anatomic terms. A great book to use is It's So Amazing! by Robie H. Harris and Michael Emberley.

Many girls come into my office knowing that periods mean monthly bleeding—but nothing else. If their moms want me to, here's what I do:

I draw a picture (sometimes on the exam table paper) of the ovaries, fallopian tubes, uterus and vagina (nothing fancy). I review where these are in her body. I say, "Every month one of the ovaries sends an egg down the tube to the uterus—and every month the uterus gets ready for the egg in case there is going to be a baby. This getting-ready process is called "making a nest."

The egg comes down and looks around for a sperm to make a baby. I don't go into detail here about how a sperm would get there unless the parent has asked me to (I talk with them separately), but it's not a bad idea to give a brief explanation if you haven't done so. What I always make clear is that I don't expect the egg to find a sperm for many years to come! "When it doesn't find one, it passes out of the body through the vagina—and so does the nest. Once the nest is gone the body starts making a new one—waiting for the next time the egg comes."

If you like, you can explain that the reason why women don't get their period when they are pregnant is because the nest is being used.
