  • Success varies with stair height and fatigue
Developing

Usually alternates feet but may need railing or occasional support

  • Uses railing for balance
  • May revert to both feet per step when tired or on unfamiliar stairs
Secure

Consistently walks upstairs alternating feet

  • Reliably alternates feet on familiar stairs
