Some babies never crawl, and it does not mean anything

Treat the sections below as a sequence. With crawling and its alternatives, getting the early decisions right makes the later ones much easier.

Not a required stage

Classic hands-and-knees crawling is one of several ways babies solve the problem of getting from one place to another. A meaningful proportion of babies never do it, moving instead by shuffling on their bottom, commando crawling on their front, rolling or simply pulling up and walking. This is well recognised by professionals and appears in guidance, though it is frequently absent from popular milestone lists.

A parent whose baby skips it can therefore spend months worrying about the absence of something that was never required. What professionals are generally interested in is whether a baby is finding a way to move, not which way they chose.

The variants

Bottom-shuffling is a common alternative, with babies propelling themselves in a seated position, sometimes at considerable speed. Commando crawling, where the belly stays on the floor and the arms do the work, often precedes proper crawling and sometimes replaces it.

On almost no sleep, some babies roll to where they want to go, which is slow, effective and disconcerting to watch for the first time. Others crawl backwards for a period before working out how to reverse the direction, which is a common and temporary frustration. None of these routes has been shown to predict anything much about later development.

Where the myth comes from

Ideas that crawling is essential for later coordination, reading or brain development circulate widely and have a thin evidential basis. Some of it derives from older developmental theories that have not held up, and some from commercial programmes built on them. Being honest about that is useful, because the myth generates real worry in parents whose babies took a different route.

This does not mean movement is unimportant; opportunity to move is consistently associated with motor development. It means the specific form of that movement matters far less than the fact that it is happening.

What actually helps mobility

Floor time is the single consistent factor, since babies cannot practise moving while being held or contained. A clear, safe area with something interesting slightly out of reach supplies both the opportunity and the motivation. Hard floors are easier to move on than deep carpet, which is worth knowing if a baby seems stuck on a particular surface.

Clothing matters more than expected, and a baby in a bulky outfit or slippery tights will make less progress on a wooden floor.

Nothing here needs buying, and equipment that holds a baby upright works against the objective.

What mobility changes in the house

The arrival of any form of independent movement is the point at which the house needs looking at from the floor rather than from standing. Stairs, cables, cleaning products, small objects, low shelves and anything unstable become live issues within days rather than weeks.

Week by week, most countries publish home safety guidance for this stage, and it is more thorough than the mental list you would compile yourself. Getting down on the floor and crawling the length of a room finds things that are entirely invisible from adult height. It is worth doing this before mobility arrives, since the arrival is usually faster than expected.

Safe sleep and feeding guidance is set nationally and updated periodically, so follow the current official guidance where you live over anything general.

When to raise it

The relevant question is not whether a baby crawls but whether they are progressing in their ability to move about over time. A baby making no attempt to move by the point your health visitor would expect it is worth raising, as is any marked asymmetry. Babies born early are considered against adjusted age, which shifts the whole timeline by however many weeks.

Developmental reviews are the natural place, and contacting earlier is fine if you are concerned. A professional who can see the baby will tell you far more than any list of ages, and they expect to be asked.

The takeaway

Care that they are moving rather than how, clear the floor at their eye level, and check anything that concerns you with a professional.

Nothing in the first year lasts, including the parts that feel permanent at three in the morning.
