Puberty timing and pace vary widely. Families can support children by using accurate names for body changes, inviting questions without embarrassment, and seeking care for early, delayed, very rapid, painful, or distressing changes.

Urgent Warning Signs - Check This First

Most puberty questions are not emergencies. Severe headache with vision changes, sudden severe pain, or a child who is unsafe or in crisis needs urgent care.

CALL 911 NOW

  • A child is unresponsive, has severe trouble breathing, a seizure, or another life-threatening emergency

  • A child has an immediate mental-health or safety crisis and cannot be kept safe

GET EMERGENCY MEDICAL CARE NOW

  • Sudden severe headache with vision changes, weakness, confusion, repeated vomiting, or a seizure

  • Sudden severe testicular or scrotal pain, swelling, or pain with nausea or vomiting

  • Heavy vaginal bleeding with fainting, marked weakness, severe abdominal pain, or possible pregnancy with pain or bleeding

CONTACT YOUR CHILD'S HEALTHCARE PROFESSIONAL TODAY

  • Puberty signs before age 8 in a child with breasts or before age 9 in a child with testicular enlargement

  • No breast development by age 13, or no testicular enlargement by age 14

  • Rapid progression, new severe acne or body hair with rapid growth, deepening voice or genital changes that concern the family

  • Breast lump, nipple discharge, persistent breast pain, unexplained weight change, fatigue, or symptoms affecting wellbeing

What Is Often Normal

  • Breast buds can be tender and may begin on one side before the other

  • Body odor, acne, pubic or underarm hair, growth spurts, and mood changes can occur as development progresses

  • A small amount of clear or white vaginal discharge may begin before a first period

  • Some teenage boys develop temporary tender breast tissue during puberty

Early and Delayed Puberty

Clinicians consider the child’s age, pattern of growth, stage of development, health history, medicines, and family pattern. Early body odor or hair alone is not always true puberty, but it is appropriate to discuss with the clinician when it occurs early or changes quickly.

Supporting Conversations

  • Start conversations early and use calm, factual language. Reassure children that questions are welcome

  • Respect privacy while remaining available. A confidential conversation with the clinician may help some adolescents

  • Discuss hygiene, periods, erections, wet dreams, acne, body image, consent, healthy relationships, and safety in age-appropriate ways

  • Do not use hormone products, supplements, or internet treatments without medical guidance

Call Preparation

  • When changes began and how quickly they are progressing; growth and weight changes; family history of early or late puberty

  • Medicines, supplements, skin products, and possible exposure to hormone creams or gels

  • Questions from the child, including emotional concerns, school concerns, or body-image distress
