Talking with your child about periods
Revisado: 4 de octubre de 2026
Solo en inglés por ahoraChildren as young as 6 or 7 can follow a simple explanation of periods. Small, regular chats make it easier to cover the facts well before a first period arrives.
Start early and keep talking
Children as young as 6 or 7 can usually follow a simple explanation of periods. Rather than one big talk, have lots of small conversations and add detail as your child grows. Natural moments make it easier, such as a question about bodies or babies, or buying pads or tampons at the shop. Answer questions in a clear, direct way. If you do not know an answer, it is fine to say so and look it up together.
What to explain
Explain that each month the lining of the womb (uterus) gets ready in case of a pregnancy. If there is no pregnancy, the lining comes away and leaves the body through the vagina as a period. A period usually lasts about 5 days, and the amount of blood is small, only a few tablespoons. Cramps are common, especially in the first days, and things like a heat pad can help.
Signs a first period is coming
Most children get their first period at around age 12, but anywhere from 8 to 15 can be normal. Every body has its own timing. A first period usually comes about 2 years after breasts start to grow. Underarm and pubic hair are other signs. White or clear discharge in their underwear often starts 6 months to a year before a first period. If you have not talked yet, this is a good time.
Getting ready together
Help your child put a pad or two in their school bag before their first period. Pads, tampons, menstrual cups and period underwear are all safe from the start, but many young people begin with pads because tampons and cups take practice. Let them know that if their period starts at school, a teacher or school nurse can help. Explain that periods are often irregular for the first couple of years, and that this is normal.
Include boys, and find what works
Boys should learn about periods too, so include sons in these talks. If talking face to face feels awkward for either of you, reading a book or watching a video together can be an easier way in. Once periods start, writing down the dates, on a calendar or in Ciclo, can help your child learn their pattern and notice anything unusual.
When to see a doctor or nurse
Book an appointment if your child is 15 and has not started their periods, or has not started within 3 years of breasts starting to grow. Also book one if your child shows signs of puberty, such as breast growth, before age 8, or has a period before 8. Also see a doctor or nurse if their periods are very heavy or still not regular after about 2 years. Severe cramps that ibuprofen does not help are another reason to go. Get urgent help if they are bleeding very heavily and feel dizzy or faint.
This is general information for parents and carers. If you are worried about your child's development or periods, talk to a doctor or nurse.
