Most babies start walking independently within 2-3 months of learning to stand up by themselves. But there are other signs, and no single developmental timeline that all babies follow. In fact, the onset of walking is extremely variable, with some babies walking before 9 months, and others waiting until they are 18 months or older.

When do babies start walking?

In the United States today, the average age of independent walking is approximately 12 months. Researchers report similar timing for babies in a number of other countries, including Argentina, Ghana, India, Norway, Oman, South Africa, and Turkey.

On average, babies in these countries take their first, unassisted steps at around 12-13 months (WHO 2006a; Ertem et al 2018).

But there are cultures where most babies begin walking months earlier – or many months later. And even within a single society, the range of individual variation can be huge.

For example, in a study tracking the development of 220 children in Switzerland, a few babies began walking independently at 8.5 months. And some babies didn’t walk until they were nearly 20 months old.

Yet all of these children experienced healthy, normal outcomes.

The timing of independent walking was unrelated the children’s later motor development and cognitive ability (Jenni et al 2013).

Of course, that isn’t always the case. Sometimes delays in the onset of walking are caused by medical conditions or developmental disorders. But most late walkers don’t have these problems. 

So what’s normal? What should we expect? How can we tell if a baby is ready to walk, and what makes some babies begin walking earlier than others?

Here’s an overview, beginning with the motor skills that babies must master before they start walking on their own. 

What are signs that a baby will walk soon?

Before they can walk, babies need to develop the strength and coordination to maintain an upright posture on their own. They also need to be able to bear most of their weight – at least momentarily – on one foot.

So babies are moving closer to independent walking when they display these motor skills:

Pulling oneself up into a standing position (by gripping furniture, or holding onto someone)


Typically, babies develop this ability about 4 months before they take their first, independent steps (Ertem et al 2018).

During early attempts, a baby will be able to remain standing for only a few seconds, and you will notice that the baby’s legs are stiff and straight (as they are in this photo).

But as the baby gets stronger, he or she will be able to stand comfortably — with knees slightly flexed — while holding on.

Walking with support


At this stage, babies have the strength to shift their weight from one leg to the other. If you hold a baby by the hands, he can walk forward. If a baby grabs onto a piece of furniture, she can “cruise,” or move along sideways.

When will a baby with these abilities begin walking independently?

Studies suggest that independent walking tends to emerge about 3 months later (WHO 2006a; Ertem et al 2018). But there’s no strict sequence that all babies follow. Some babies begin walking with support relatively early — even before they have learned to crawl. For these babies, the next stage might be independent walking. But babies might also shift their focus to crawling (WHO 2006b).

Standing alone (at least momentarily).


How long after learning to stand unassisted do babies begin to walk?

International studies suggest that most babies start walking within 2-3 months of learning to stand (Ertem et al 2018). But it isn’t the absolute passage of time that matters so much. It’s the sheer amount of practice and hard work.

When babies are learning to walk independently, they fall down. A lot. Some babies don’t seem to mind much. They enthusiastically throw themselves into the project, and learn to walk rather quickly — sometimes within a few days of learning to stand. 

What about crawling? Do babies have to crawl before they can walk?

Absolutely not. In fact, some babies never crawl. Read more about it in my article opens in a new window“When do babies crawl, and how does crawling develop: An illustrated guide.”

So when can babies walk with support?

International research suggests that approximately half of all babies have begun walking with support by the time they are 9 and half months old (WHO 2006a; Ertem et al 2018). But local norms vary.

In cultures where parents actively teach their babies to walk, infants may begin assisted walking by 7-8 months (e.g., Super 1976).

In places where parents take a more hands-off approach, the average onset of walking with support is later – closer to 10.5 months (WHO 2006a).

And in cultures where babies remain physically restrained throughout the day – in carriers, slings, cradles, and other devices – babies don’t begin walking until much later.

When do babies make the transition to independent walking?


As noted in the introduction, there is a wide range of variation here. Some babies begin before they are 9 months old. Others take 18 months or more.

Why is there so much variation, and what sort of factors predict whether a child will walk earlier or later?

Human bipedalism is a difficult trick to learn. Babies face many obstacles, including their own bodies.

For instance, a baby with skinny legs – and a higher muscle-to-fat- ratio – will have an easier time fighting gravity, and may begin walking sooner than a plumper, less muscular infant (Adolf 2008).

The timing of walking also depends on opportunities for movement and practice.

In general, babies who get more exercise – time outside a sling, crib, or cradle – tend to achieve motor milestones earlier in life. More specifically, babies learn to walk earlier if they get lots of practice with “assisted walking” — taking steps forward while someone holds their hands.

Motivation is probably important, too. For example, researchers have found that babies are more likely to start learning to walk if they show an interest in accessing distant objects (Karasik et al 2011).

And something as mundane as clothing can make a difference.

Experimental research confirms that it’s harder for babies to walk when they are wearing diapers. The bulk gets in the way – forcing them to waddle with their legs farther apart – and babies are more likely to lose their balance and fall (Cole et al 2012).

Together, these factors can help explain why babies vary as individuals. They can also shed light on some of the dramatic differences we observe between cultures.

How do parenting practices affect the development of walking?

Consider the Kipsigis of Kenya, people who raise crops and herd cattle. In this culture, parents actively encourage infants to develop motor skills essential for walking.

It begins with something called the stepping reflex: Hold a newborn baby upright – allowing his or her feet to touch the ground – and the baby will appear to take alternating steps. As if the baby is ready to walk!

Of course, the baby isn’t really ready to walk, not yet. Young babies lack the muscle development, coordination, and body proportions to walk successfully when they are very young. And if we simply ignore this stepping response, the behavior will eventually fade.

In Western countries, for example, the stepping response usually disappears by the time babies are 8 weeks old.

But the Kipsigis don’t ignore the stepping reflex. Instead, they turn it into a game. Supporting babies by the armpits, mothers bounce their babies on their laps, stimulating the stepping reflex.

The games start when babies are about one month old, and babies experience daily practice. By the time they are 7-8 months old, infants are strong enough to begin walking (with support) on the ground.

There is never a point when babies lose the stepping response. Instead, there is a continuous, gradual development of ever-stronger stepping (Super 1976).

When researchers tested a similar approach on babies living in the United States, they noticed the same thing: Babies didn’t lose the stepping response over time, not when they were encouraged to practice it (Zelazo 1983).

And in both groups — Kipsigis and Americans — researchers observed a relationship between practice and the timing of walking. Babies who practiced step-walking tend to walk independently at an earlier age (Super 1976; Zelazo 1983).

So parents can stimulate the development of walking through exercise and play. And the reverse is true as well:

When babies experience movement restriction – by being held, swaddled, or immobilized every day – they begin walking later (Adolph and Robinson 2013).

For an extreme case, consider the Ache of Paraguay, people who practiced hunting and gathering until the late 20th century.

When they were living in the old, traditional way, the Ache carried their babies almost constantly. They regarded their environment – the Amazonian rain forest – to be too dangerous to set infants down.

So Ache babies didn’t get opportunities to practice walking, and, as a result, children didn’t learn to walk until they were approximately 24 months old (Kaplan and Dove 1987).

I call this an extreme case, but “extreme” is a relative term: It depends on what populations you use for comparison. The Ache aren’t the only hunter-gatherers who avoided setting their babies on the ground. And people in other societies follow customs that restrict infant movement.

For instance, throughout Central Asia, babies spend long hours each day restrained in a traditional cradle called a “gahvora” (Karasik et al 2018).

In different times and places, it might have been pretty common for babies to miss out on the sort of experiences that lead to early walking. And that should make us re-evaluate our ideas about what constitutes “normal” development.

It doesn’t make sense to talk about “normal” timing in a vacuum, as if local differences in the environment don’t matter.

When should a parent be concerned? At what point is a child considered to have developmental delay?

Organizations like the American Academy of Pediatrics recommend that you talk with your doctor if your baby can’t walk by the age of 18 months. And that’s good advice. Sometimes, being “slow to walk” is a sign of a physical problem, so it’s good to investigate early, and take action.

But keep in mind: Most babies who haven’t yet begun walking at 18 months do not suffer from developmental problems. Not if they are otherwise healthy.

As we’ve seen, babies don’t learn to walk on a fixed time schedule. The timing can vary dramatically from one individual to the next. The same is true for many other motor skills. To learn more about it, see my article on opens in a new windowbaby motor milestones.
