My Baby Bum Shuffles Instead of Crawling
The short answer
Bottom shuffling (bum shuffling) is a normal alternative to crawling used by about 9% of babies. Bottom shufflers often walk later than crawlers, typically around 18 months, but they develop perfectly normally. It tends to run in families and is not a sign of a developmental problem.

By Age
What to expect by age
Some babies start bottom shuffling as soon as they can sit independently. They discover that by using their hands or feet, they can scoot across the floor on their bottom. This is a valid form of early mobility. Bottom shufflers often dislike tummy time and skip the traditional crawling stage entirely.
Your baby may be an efficient bum shuffler by now, scooting across the room at impressive speed. Research shows that bottom shufflers are typically independent sitters who found a way to get around without going through crawling. This is completely normal. Bottom shuffling often runs in families, so ask if anyone else in your family was a bum shuffler.
Bottom shufflers tend to walk a bit later than babies who crawled on hands and knees. If your baby is still shuffling and not yet walking, this is expected. Many bum shufflers walk between 15 and 18 months. As long as your baby is pulling up and showing interest in standing, they are on track.
Most bottom shufflers are walking by 18-21 months. If your baby is not yet walking by 18 months, your pediatrician may recommend an evaluation, but many healthy bum shufflers simply start walking later. If your child is pulling to stand and cruising, walking will likely come soon.
What Should You Do?
When to take action
- Your baby bottom shuffles and can also sit independently with good balance.
- Your baby uses both sides of their body equally when shuffling.
- There is a family history of bum shuffling or late walking.
- Your baby is pulling to stand and cruising, even if not yet walking independently.
- Your baby is over 18 months, still bottom shuffling, and not walking independently.
- Your baby seems unable to pull to stand or shows no interest in upright mobility.
- Your baby only shuffles in one direction or favors one side of their body.
- Your baby was previously walking or crawling and has reverted to only bottom shuffling.
- Your baby seems to have weakness in their legs or cannot bear weight when held standing.

My Baby Scoots Instead of Crawling
Some babies skip traditional hands-and-knees crawling entirely and scoot on their bottoms, army crawl on their bellies, or invent other creative ways to get around. As long as your baby is moving independently and exploring their environment by 12 months, the method they choose doesn't matter. Many bottom-scooters go straight to walking and never crawl at all.
My Baby Isn't Crawling Yet
The age range for crawling is huge - some babies crawl as early as 6 months, others not until 10-11 months, and some skip crawling entirely and go straight to walking. What matters most is that your baby has some form of independent mobility (scooting, rolling, army crawling) by around 12 months and is exploring their environment.
My Baby Isn't Walking
The normal range for first independent steps is huge - anywhere from 9 to 18 months, and all of it is considered typical development. Many parents feel pressure when they see other babies walking early, but a baby who walks at 15 months is just as healthy as one who walks at 10 months.
My Baby Seems to Use One Side More Than the Other
Babies should use both sides of their body fairly equally during the first 18 months of life. While slight preferences can be normal, a consistent pattern of favoring one side - using one arm much more than the other, crawling with one leg dragging, or turning the head predominantly one way - should always be discussed with your pediatrician. Early identification of asymmetry leads to the best outcomes.
My Baby Only Army Crawls
Army crawling (also called commando crawling) is a completely valid and normal way for babies to move. Many babies army crawl for weeks or even months before transitioning to hands-and-knees crawling, and some skip hands-and-knees crawling entirely. What matters is that your baby is independently mobile and exploring their environment.
One Side of My Baby's Body Moves Differently
Babies should generally use both sides of their body equally. If one side consistently moves differently, is weaker, stiffer, or less coordinated, this warrants evaluation. Asymmetric movement can indicate hemiplegia (cerebral palsy affecting one side), brachial plexus injury, or other neurological conditions that benefit from early therapy.
