Toddlers & Stairs: When They Climb & How to Stay Safe | Parenting Hub

Most toddlers climb stairs from 12–18 months. Here's the developmental progression and the home safety setup that prevents the most common falls.

Stair climbing follows a clear stair-by-stair progression. Falls from stairs are one of the most common toddler injuries — gates, supervision and teaching the climb all matter.

Typical progression

  • 12–15 months: crawls up stairs with supervision
  • 18 months: walks up holding a hand or rail (two feet per step)
  • 2 years: walks down holding a hand
  • 3 years: walks up alternating feet; down alternating by 3.5–4 years

Safety setup

  • Stair gates at top and bottom until age 2
  • Top gate must be hardware-mounted, not pressure-fit
  • Teach 'feet first' bottom-shuffle for coming down before they walk down
  • Practise on a single step before tackling full flights
  • Keep stairs clear of toys, clothes and clutter

When to see a doctor

Talk to your GP if a toddler over 2 years cannot walk up stairs holding a rail, frequently falls without an obvious reason, or shows leg weakness or limping.

When to seek help

  • Can't walk up stairs with help by age 2
  • Frequent unexplained falls
  • Limping or leg weakness
  • Loss of stair skills

Common questions

Pressure-fit or screw-in gates?

Always hardware-mounted at the top of stairs. Pressure gates can be pushed out by a lunging toddler. Pressure gates are fine at the bottom or between rooms.
