Bum Shuffling Instead of Crawling

It is a recognised way of moving, not a failure to crawl

The NHS says it in one line on its Baby Moves page: "Your baby will probably start crawling (although not all babies crawl – some shuffle around on their bottoms) at around 7 to 10 months." That parenthesis is doing a lot of work. Bottom shuffling is not an exception the NHS tolerates; it is listed as one of the normal outcomes.

The HSE goes further and counts it. Its twelve-month trigger for contacting a GP or public health nurse is a baby who "has no form of independent mobility (such as crawling, commando crawling, bottom shuffle)". Bottom shuffling is on the inside of that list, not the outside. A twelve-month-old who shuffles competently around the room has independent mobility by the HSE's own definition.

The AAP describes the same thing from the other side of the Atlantic: "A few children never crawl. Instead, they use alternative methods, such as scooting on their bottoms or slithering on their stomachs. As long as your baby is coordinating each side of her body and using each arm and leg equally, there's no cause for concern."

Why some babies shuffle

Shuffling tends to appear in babies who sit early and well, dislike being on their tummy, or have loose, flexible joints that make the hands-and-knees position feel unstable. It is efficient: a sitting baby who wants a toy across the room can get there without ever changing position or losing the view.

It also runs in families. That is a widely reported clinical observation rather than a figure any health body publishes, so we will not attach a percentage to it. What is published is that hands-and-knees crawling is not universal at all. The WHO's motor development study recorded that 4.3% of the healthy children it followed never showed hands-and-knees crawling — the only one of its six milestones that a meaningful number of children skipped entirely.

Do bottom shufflers walk later?

Often, yes — and the honest answer is that no national health body publishes a figure for how much later. The WHO windows give the range for walking alone in the general population: 8.2 months at the 1st percentile, 12.0 months at the median, and 17.6 months at the 99th. Shufflers cluster towards the later end of that distribution, but the study did not break its walking data down by whether a child crawled first, so any specific "shufflers walk at X months" claim you read is not coming from it.

What can be said is that the referral threshold does not move for shufflers. NICE names "not walking by 18 months (corrected for gestational age)" as a commonly delayed motor milestone and says to refer children with delayed motor milestones for assessment. That number applies to a shuffler exactly as it applies to a crawler.

What to check while your baby shuffles

Two things, both of which come from the guidance rather than from folklore.

Symmetry. The AAP's condition is that a baby is "coordinating each side of her body and using each arm and leg equally". NICE lists "asymmetry or paucity of movement" among possible early motor features of cerebral palsy. A shuffler who always pushes with the same leg and drags the other, or who only ever uses one hand to propel themselves, is worth mentioning.

Weight-bearing. The HSE's nine-month list includes a baby who "cannot take weight on their legs when they're held in a supported standing position". Shufflers sometimes resist standing simply because they have not practised it, but a baby whose legs give way entirely, or who holds them stiffly crossed, should be looked at.

Should you try to make them crawl?

No guidance anywhere tells parents to stop a baby shuffling or to train crawling. The AAP's suggestion is gentler and applies to any baby: put "in­triguing objects just beyond her reach", and build small obstacle courses from pillows and cushions as they get more agile. Floor time and interesting things at a distance do more than any technique.

What the AAP does warn against is baby walkers, which it says "do not help children learn to walk. They actually eliminate the desire to walk", and which it "strongly urges parents not to use". A stationary activity centre without wheels is the alternative it names.

If your baby was born early

All the ages above should be counted from the due date. The HSE's example: a ten-month-old born two months early has a corrected age of eight months. NICE writes its motor thresholds "corrected for gestational age", and the AAP advises using adjusted age until two years, when most children born preterm have caught up.

The line that actually matters

The NHS gives one clear instruction on this page: "If you're worried that your baby isn't showing any signs of moving by 12 months, ask your health visitor for advice." The HSE's version at twelve months is the same, with bottom shuffling explicitly counted as moving. A baby who shuffles is not the baby that sentence is about.

And as ever, the trigger that beats every age: if your baby loses a skill they already had, contact a GP, health visitor or public health nurse rather than waiting for the next review.

What shuffling changes around the house

A shuffler is mobile, which means the babyproofing timetable is the same as for a crawler even though the milestone chart says they have not crawled. Shufflers reach sockets, cables, bins and stairs at the same age crawlers do, and they usually do it faster over smooth floors. The stair gates go up when the shuffling starts, not when the crawling does.

Shuffling also affects clothing more than crawling does. Trousers wear through at the seat, and a baby dragging themselves across a hard floor in a sleepsuit gets less grip than one on hands and knees. Bare legs or shorts on a carpet give better traction than slippery fabric, which is a small thing that occasionally unlocks a baby who seems stuck.

Does it matter that they missed crawling?

Nothing in NHS, HSE, NICE or AAP guidance says that crawling is a required stage or that skipping it causes later problems. Claims that missing crawling harms reading, coordination or brain development are not made by any of those bodies, and we are not going to repeat them. The AAP's framing is the one to hold on to: what matters is that a baby "is able to explore her sur­roundings and is strengthening her body in preparation for walking". Bottom shuffling does both.
