When Do Babies Start Walking? WHO Developmental Norms

One of the most googled parenting questions at 3am: "My baby is 14 months and still not walking — is something wrong?" Often, the answer is no — but context matters, and understanding the actual range helps.

The WHO Gross Motor Milestone Timeline

The WHO Multicentre Growth Reference Study tracked children from six countries across different cultures and diets. Their finding: the window for normal development is wide.

Milestone	Early (P1)	Average (P50)	Late (P99)
Sits without support	4.0 mo	5.9 mo	9.2 mo
Stands with assistance	4.8 mo	7.6 mo	11.4 mo
Hands-and-knees crawling	5.2 mo	8.3 mo	13.5 mo
Walks with assistance	6.0 mo	9.2 mo	13.7 mo
Stands alone	6.9 mo	11.0 mo	17.6 mo
Walks alone	8.2 mo	12.1 mo	17.6 mo

What Comes Before Walking

Walking doesn't happen in isolation. It's the result of months of muscle development, balance practice, and coordination building.

0–3 months: Building a foundation

Babies develop head and neck control. Tummy time is essential here — it strengthens the muscles that will eventually support walking. Aim for short sessions several times a day, increasing as your baby gets stronger.

3–6 months: Core strength

Babies begin pushing up on their arms during tummy time, rolling over, and bearing weight on their legs when held standing. Don't be alarmed if your baby doesn't love standing — some don't.

6–9 months: Sitting and pulling up

Independent sitting happens around 6–7 months on average. Babies begin pulling themselves to standing using furniture — "cruising" often follows shortly after.

9–12 months: Cruising

Cruising (walking while holding furniture) is the final stage before independent steps. This phase can last days or months. Your baby is figuring out balance, weight shifting, and what happens when they let go.

12–18 months: First steps

Most babies take their first independent steps somewhere in this window. First steps are wobbly, wide-legged, and arms-out — perfectly normal. Walking competence (smooth, confident gait) usually takes another 2–3 months after first steps.

Normal Variations in How Babies Learn to Walk

Not all babies crawl. Some scoot on their bottom, roll everywhere, or bear-walk (hands and feet). These are all normal alternatives — crawling is not a required milestone.

Bottom shufflers (babies who scoot in a sitting position) often walk later than crawlers, sometimes at 18 months. This is still within the normal range.

Signs That Warrant a Pediatrician Visit

Contact your doctor if your baby:

• Is not sitting independently by 9 months
• Is not pulling to stand by 12 months
• Is not walking by 18 months
• Loses a motor skill they previously had (regression is always worth investigating)
• Has significantly asymmetric movement — using one side noticeably more than the other
• Has very stiff or very floppy muscle tone

How to Support Motor Development

Floor time over everything. Floor time gives babies more chances to practice the movements that support motor development. They need the challenge of working against gravity.

Barefoot is better. When learning to walk, bare feet or soft-soled shoes give the best sensory feedback for balance. Hard-soled shoes can actually hinder walking development.

Don't hold their hands constantly. It feels supportive, but babies learn balance by falling (safely). Let them practice standing and stepping with you nearby, not with you holding them up.

Follow their lead. If your baby isn't interested in standing yet, don't force it. Motor development follows its own schedule.

Tracking Milestones Over Time

The hardest part of developmental monitoring is that a single observation doesn't tell you much. What matters is the pattern — are skills emerging and building on each other?

Keeping a record of when your baby first sits, pulls up, cruises, and takes steps — in a baby milestone tracker or even a simple note — helps you see the trajectory clearly. For the behavior changes that often happen around new abilities, see baby developmental leaps. When your pediatrician asks at the 12-month visit, you'll have real dates, not vague memories.
