Crawling milestones: when babies crawl, the different styles and what to do if they skip it
Watching a baby figure out how to get somewhere they want to be is one of the joys of the first year. Crawling is often the first form of independent movement, and yet it arrives in so many different shapes that it can be hard to know what "normal" looks like. The short answer is: the range is genuinely wide, the styles are genuinely varied, and a great many babies take an entirely different route to walking altogether. Here is what to expect and when, if ever, to mention anything to your health visitor.
When babies typically start to crawl
The most common window for the start of crawling is somewhere between seven and ten months. That is when the largest number of babies begin to move around on all fours, though you will find perfectly healthy babies who start earlier or later than this range.
Some babies are on the move as early as six months, usually with a belly-to-the-ground style before their arms are quite strong enough to hold their body up. Others are still not crawling at eleven or twelve months and go on to walk independently without ever crawling at all. Both are recognised developmental paths. The CDC's developmental milestones framework and the AAP both describe crawling as one possible route to mobility, not the only one.
What matters most is that your baby is becoming more mobile over time, in whatever way works for them. A baby who is rolling, shuffling, scooting, or pulling to stand is a baby who is developing well, whether or not classic hands-and-knees crawling is part of their story.
The different crawling styles
Babies are remarkably inventive when it comes to getting from one place to another. Here are the most common styles you might see, all of which are completely valid forms of locomotion.
- Classic hands-and-knees crawl. The most familiar style: weight on both hands and both knees, moving opposite arm and leg together. This is what most people picture when they think of a crawling baby, but it is only one of several approaches.
- Commando or belly crawl. The baby pulls themselves forward with their arms while their belly stays on the floor. This often comes before the hands-and-knees style as babies are still building the arm strength to lift their torso.
- Bum shuffle. A very popular alternative, particularly common in some families. The baby sits upright and propels themselves forward using their legs and sometimes one arm, scooting along on their bottom. Bum shuffling runs in families and is associated with slightly later walking, but it is not a cause for concern.
- Rolling as transport. Some babies work out that rolling repeatedly gets them where they want to be. This is an early and entirely legitimate form of independent movement.
- Crab crawl. Moving sideways rather than forward, often using one strong arm to lead. Some babies never go straight ahead; they crab-crawl quite efficiently for a period before switching to other styles.
- Bear crawl. Hands and feet on the floor with knees lifted, bottom high in the air. This takes considerable arm and leg strength and tends to appear a little later, sometimes as a step toward standing.
If your baby has landed on a style that is not listed here, that is fine too. Babies are creative, and the goal is movement, not a specific technique.
Why bum shufflers tend to walk later
Parents of bum shufflers sometimes notice that their baby walks later than peers who crawled on all fours, and that is a real pattern rather than a coincidence. The reason is largely one of motivation: bum shuffling is an extremely efficient way to get around. A baby who has mastered it can move quickly, carry toys in both hands, and watch the world from an upright sitting position all at the same time. Why would they bother learning something new?
The typical walking age for bum shufflers is around 18 months, compared to the more commonly cited average of around 12 months for babies who crawled on all fours. This later start is within the normal range and is not associated with any developmental difficulty.
Whatever style of movement your baby has chosen, if they have not taken any independent steps by 18 months, it is worth mentioning to your GP or health visitor, regardless of their crawling history. This is not a cause for alarm, simply a useful checkpoint.
How tummy time supports crawling
Tummy time and crawling are closely connected. The shoulder, arm, and core strength that a baby needs to hold themselves up on all fours is built during all those minutes spent lifting their head and pushing up on their arms during floor play on their front.
The good news is that tummy time does not have to be a difficult daily battle. Short, frequent sessions work better than long ones. A few things that tend to make it genuinely enjoyable rather than just endured:
- Get down to their level. Lying on the floor facing your baby gives them the most interesting thing in their world to look at: your face. Babies are far more motivated to lift their heads when there is a person there.
- Use a mirror. A small unbreakable mirror placed in front of a baby is a reliable source of fascination. The baby in the mirror keeps doing exactly what they do, which turns out to be compelling.
- Place a toy just out of reach. Not frustratingly far, just enough to make reaching feel worth the effort. This encourages the reaching and weight-shifting movements that build toward crawling.
- Keep sessions short. Two minutes of engaged, happy tummy time five times a day is more useful than ten miserable minutes once. A session that ends before tears is a successful one.
As your baby's arms and core get stronger, you will notice them starting to rock forward on all fours, then perhaps lurch a step or two. This trial and error is how crawling begins.
Encouraging movement without forcing it
The most useful thing you can do to support your baby's movement is to give them the time and space to practise on their own terms. A safe, clear floor area with interesting things slightly out of reach is all that is really needed.
Babies who spend a lot of their waking time in bouncers, jumperoos, or walkers have fewer opportunities to practise independent floor movement. These things are enjoyable and convenient, and they do not cause developmental harm in reasonable amounts. But floor time genuinely matters. A baby cannot discover crawling while strapped into a seat, however stimulating that seat might be.
There is no technique to teach, no exercise program to follow. Babies learn to crawl by attempting it, falling, adjusting, and attempting it again. The most productive role you can play is to create the conditions for that exploration: a safe floor, interesting things to reach for, and your presence nearby.
If your baby seems to be skipping crawling
Some babies go from sitting to pulling up to standing to walking without any crawling in between. This is a recognised and normal developmental path. Research has not found any link between skipping crawling and later difficulties with reading, coordination, or learning, despite claims that occasionally circulate.
The question worth paying attention to is not whether your baby crawls, but whether they are becoming more mobile over time in some way. A baby who is rolling, shuffling, or pulling to stand is developing their independent movement skills, even if crawling is not part of the picture.
If your baby is not showing any independent mobility at all, meaning they are not rolling, not shuffling, not scooting in any direction, by nine to ten months, that is worth mentioning to your health visitor at your next check. This is not a signal that something is wrong, but a prompt for a conversation. Most of the time there is a straightforward explanation, and getting a professional view early is always better than wondering.
What comes after crawling
Once a baby is mobile on the floor, the next natural steps are pulling to stand, cruising along furniture, and eventually letting go and taking those first unsteady independent steps. The timing of this sequence varies enormously from baby to baby.
Some babies crawl for a week before discovering they can pull themselves up on the sofa and switching their attention almost entirely to standing. Others crawl happily for months before showing any interest in an upright position. Both are normal. The average age for first steps is around 12 months, but a healthy range runs from roughly nine months to 18 months.
The transition from crawling to walking is rarely smooth or linear. Expect regressions back to crawling when your baby is tired, when they want to move quickly, or when the floor is slippery. Crawling remains a useful, efficient form of transport for a long time after walking begins, and many toddlers switch between the two for months.
Frequently asked questions
At what age do babies start to crawl?
Most babies start to crawl somewhere between seven and ten months, though the range is wide. Some babies are on the move as early as six months, and others are closer to twelve months. A small number skip crawling altogether and go straight to pulling up and walking, which is also completely normal.
Is bum shuffling instead of crawling normal?
Yes. Bum shuffling is a very common alternative to hands-and-knees crawling. It tends to run in families, and babies who shuffle are simply choosing a different, equally valid form of locomotion. Bum shufflers often walk a little later than crawlers, usually by around 18 months, which is still within the normal range.
What if my baby skips crawling altogether?
Skipping crawling and going straight to pulling up and walking is a recognised normal developmental path. Research has not found any connection between skipping crawling and later problems with learning or coordination. If your baby is walking independently by 18 months, there is nothing to worry about.
How does tummy time help with crawling?
Tummy time builds the shoulder, arm, and core strength that hands-and-knees crawling requires. Babies who spend regular, supervised time on their fronts while awake develop the muscle groups they will need to lift and propel themselves. Short, frequent sessions are more effective than occasional long ones, and making them enjoyable by getting down to your baby's level makes a real difference.
When should I be concerned that my baby is not crawling?
Not crawling on its own is not a concern, especially if your baby is moving around in other ways. The range for independent mobility is wide. If your baby is not showing any independent movement at all, such as rolling, shuffling, or scooting in any direction, by nine to ten months, it is worth a conversation with your health visitor. Always follow your doctor's or health visitor's guidance for your individual baby.
Do babies need special flooring or mats to learn to crawl?
No special flooring is needed. A clean, firm surface such as a carpet or a foam play mat is ideal. The main thing is that the surface is firm enough for your baby to push against. Very soft surfaces like deep-pile rugs can make it harder for a baby to generate the push they need to move forward. Mats with a little cushioning are fine and protect knees as babies start to move around more.
