Puberty typically begins between ages 8 and 13 in girls and 9 and 14 in boys, though there's a wide range of what's considered normal. Early puberty (before these ages) or delayed puberty (starting significantly later) can sometimes be a normal individual variation, but occasionally relates to an underlying hormonal or medical condition worth investigating.

What is Early or Delayed Puberty?
Puberty typically begins between ages 8 and 13 in girls and 9 and 14 in boys, though there's a wide range of what's considered normal. Early puberty (before these ages) or delayed puberty (starting significantly later) can sometimes be a normal individual variation, but occasionally relates to an underlying hormonal or medical condition worth investigating.
A doctor can assess whether the timing of puberty falls within the normal range for your child, or whether further investigation is needed to identify and address any underlying cause.

Clinical context
There's a wide range of what's considered normal timing

Practical steps
Emotional Support Matters Alongside Any Medical Assessment
Early or delayed puberty compared to peers can be emotionally difficult for children and teenagers — open, supportive conversation alongside any medical assessment helps them feel understood.
- 1Seek assessment if timing seems outside the typical range.A GP or paediatrician can assess and, if needed, refer to a specialist.
- 2Consider family history.Puberty timing often runs in families, which can be a reassuring or relevant piece of information.
- 3Provide emotional support.Being notably earlier or later than peers can be difficult for a child — listening and reassurance help.
- 4Follow specialist guidance if an underlying cause is found.Some causes of early or delayed puberty have specific, effective treatments.

BarnMD Bottom Line
There's a wide normal range for puberty timing, and while it's often simply individual variation, assessment can identify and address any underlying cause when needed.
Emotional support for your child is just as important as any medical assessment during this process.
