Answer:

For girls, physical changes sometimes start happening as young as eight years,  or you might see these changes only now, as your child enters the teenage years. Physical changes in puberty include:

breast development

changes in body shape and height

growth of pubic and body hair

the start of periods.

For  boys, physical changes usually start around 11-12 years – but any time between 9 and 14 years is normal. Physical changes include:

growth of the penis and testes (testicles)

changes in body shape and height

erections with ejaculation

growth of pubic, body and facial hair

voice changes.
