FirstWeeksYour baby at 55 weeks: mile collector
Medically-informed · Sources: CDC · Updated June 2026
Walking (or nearly): distance and confidence compound daily, and the world reorganizes around a mobile toddler.
What’s happening
The gait timeline
Wide stance and high arms first; smoother stride, stopping without sitting, and carrying-while-walking come over the next months. Falls remain constant; concern doesn't.
Outdoor upgrade
Grass, sand, slight slopes — uneven terrain is balance training no toy can match. First real shoes: flexible, roomy, only for outside.
Climbing escalates
Chairs, couches, stairs, you — everything is a route. Spotting beats forbidding: teach feet-first-down as the house rule.
What to do
- Daily outdoor walking time, terrain varied
- Buy shoes measured, flexible, and slightly roomy
- Practice backwards-down on stairs together, every time
When to check in
Falls with head bumps: crying-then-normal reassures; vomiting, sleepiness, or acting off afterwards — call now.
