  • Skim the Milestone map for your child's age.
  • Bookmark the Getting help pathway for when you need it.

If you are worried

  • Bring the Before a check-up checklist to your GP or nurse.

Who this guide is for

Mums, dads, partners, grandparents, foster and kinship carers, single parents, same-sex parents, breastfeeding and formula-feeding families, culturally and linguistically diverse families, Aboriginal and Torres Strait Islander families, families raising neurodivergent children, families of children with developmental delay or disability, and any caregiver who loves a child from birth to 5 years.

The calm version

Development is the everyday way children grow, move, communicate, think, play, relate and manage feelings. The first five years matter because warm, responsive relationships and small daily experiences shape a child's brain, learning, health and behaviour for years to come. Children develop at different rates. Milestones are guideposts, not a parenting scorecard. [1][2][9]

What matters most

  • Warm, responsive relationships and being known by safe adults.
  • Everyday play, talk, songs, books and shared attention.
  • Plenty of movement, outdoor time and active floor play.
  • Enough sleep, food and gentle routines.
  • Limited passive screen time and lots of live conversation.
  • Regular child health checks and listening to parent worry. [1][4][9][10][14]

Why early support helps

  • The first 5 years are a sensitive time for brain development.
  • Small targeted help often works better than waiting for years.
  • Support does not need a diagnosis — concern is enough.
  • If your child loses skills they once had, ask for advice promptly.
  • If you feel something is not right, you can ask a professional now. [2][6][11][12]

Variation is normal — and so is asking

Some children walk early, some talk late, some are quieter, some are louder. Variation is part of childhood. But if a milestone is well outside the usual range, if concerns sit across more than one area, or if your child loses a skill, asking your GP or child and family health nurse is a kind, sensible next step.
