02Steps

1. Start before it starts

   DadPuberty usually begins between 8 and 13 for girls and between 9 and 14 for boys, so aim for the first talk around 8 or 9. Start by asking: “What have you heard at school about bodies changing?” Find out what they know before you add anything.

2. Use the real names

   DadSay penis, testicles, vagina, vulva, breasts and period in the same voice you'd use for elbow. Keep it brief and calm. “These changes are normal. Everybody goes through them, each on their own schedule.”

3. Cover both bodies

   DadEvery kid should know what happens to everyone. Girls: breast buds, some discharge, then periods. Boys: testicles grow first, then voice cracks, surprise erections and wet dreams, which happen in sleep and aren't their fault. Both: hair, sweat, pimples and a growth spurt.

4. Hand over the hygiene kit

   Dad showsKid copiesGive them the pouch. “Sweat starts to smell now. Deodorant every morning, and a shower with soap and shampoo after sports and most days.” Before handing anyone a razor, show them how: wet skin, shaving gel, light pressure, never share a razor.

5. Talk about periods too

   DadDads can do this. With a daughter, open a pad and show how it works before her first period. Put supplies in her backpack and remind her the school nurse can help. With a son, explain periods plainly so he knows they're normal and nothing to joke about.

6. Privacy and their body

   TogetherKnock before you go into their room, and give them privacy in the bathroom. Say: “Your body belongs to you. Nobody touches you without your okay, and you ask first before touching anyone else.” With older kids, talk about consent in plain words.

7. Keep the door open

   DadEnd with: “You can ask me anything, even the embarrassing stuff. If I don't know, we'll look it up together.” Good places to look: their pediatrician, HealthyChildren.org and MedlinePlus. Then bring it up again next month, in the car.

03If it stalls

• If they groan, “Dad, I know,” say, “Great. Tell me what they taught you,” and fill in the gaps.
• If they ask something you can't answer, say, “Good question. Let me find out,” and come back with it.
• If it gets too awkward, stop. A two-minute talk now and another next week beats one long one nobody wants.
• If your kid would rather ask someone else, that's fine. Offer a relative, a family friend or their pediatrician, and keep the kit stocked.

• Typical ages and the order of changes. MedlinePlus (NIH) says puberty usually happens between ages 8 and 13 for girls and 9 and 14 for boys; in girls breast development usually comes first and periods last; in boys the testicles and penis grow first, then hair, muscle, a deeper voice and facial hair; and both may get acne and a growth spurt.

• Girls: periods, supplies, deodorant, shaving. The AAP says puberty often begins earlier than parents think, to start conversations early, that breast buds are a good time to talk about periods, to put pads and liners in a locker or backpack and explain how to use them before the first period, to see the pediatrician for severe cramps, that most girls start deodorant at the start of puberty and shower more often, how to teach safe shaving, and to call the pediatrician for changes before 8 or none by 13.

• Boys: wet dreams, erections, privacy, no teasing. The AAP says wet dreams happen during sleep and should be explained without blame, that unexpected erections are normal and become less frequent, to respect a preteen's privacy and knock before entering, to avoid even good-natured teasing about body changes, and to watch for a negative body image, which can lead to eating disorders.

• Real names, short honest answers, consent. The AAP advises finding out what your child already knows, keeping answers brief and honest, using proper names for all body parts, teaching body autonomy and asking for a “yes” before touching others, talking about consent by ages 8 to 9, using everyday teachable moments, and asking a relative, family friend or pediatrician to help if you're uneasy.
