Quick answer: Most babies crawl between 7–10 months, but the normal range extends to 12 months. Some babies skip crawling entirely and move straight to pulling up and walking — this is a normal developmental variant, not a delay.
The developmental prerequisites
Crawling requires a specific set of skills to come together: core strength from tummy time, bilateral coordination (using both sides of the body together), weight-bearing on hands and knees, and proprioceptive awareness of limb position. These capabilities develop progressively — you can’t rush crawling without the foundation work, but tummy time from birth builds the physical capacity significantly faster than leaving a baby on their back all day.
Crawling styles: all valid
Classic crawling (hands and knees, contralateral movement — right hand, left knee together) is one of many normal locomotion patterns. Bottom shuffling (sitting upright, using hands to push along the floor), commando crawling (belly on the floor, pulling with arms), bear walking (hands and feet, bottom in the air), and rolling as a form of transport are all normal developmental variants. Babies who bottom-shuffle tend to walk later (14–18 months on average vs 12 months) but are not developmentally delayed. The key indicator of healthy development is forward progression, not the specific movement pattern.
The role of tummy time
Babies who have regular supervised tummy time from birth develop the strength and midline crossing skills needed for crawling significantly faster than those who spend most of their time on their back or in bouncers and car seats. If a baby is rarely placed on their tummy during the day, they may reach 7–8 months without the upper body strength needed to push up into a crawling position. Starting tummy time even at 5–6 months (late, but not too late) still makes a meaningful difference.
When to flag to your doctor
Discuss with your doctor or pediatrician if: your baby is not showing any form of forward locomotion by 12 months; there is no weight-bearing when held standing by 9–10 months; there is no pulling to stand by 12 months; or there are other developmental concerns (no babbling, no pointing by 12 months). A baby who was crawling and then stopped is a more significant concern than one who is simply taking their time to start — regression of motor milestones warrants prompt assessment.
Frequently Asked Questions
My 11-month-old isn’t crawling — should I be worried?
Not necessarily. 11 months is within the normal range for crawling onset. If your baby is showing other signs of mobility and strength (pulling to stand, cruising along furniture, bottom shuffling) and is meeting social and communication milestones, this is typically a variation in locomotion pattern rather than a delay. Discuss with your pediatrician at the 12-month check.
Does skipping crawling affect development?
Research does not support the claim that skipping crawling causes learning or reading difficulties. Some occupational therapists believe contralateral crawling supports neurological development; the evidence base for specific crawling requirements for later skill development is not robust. Babies who go directly from sitting to walking do so without measurable developmental disadvantage.
How can I encourage crawling?
Maximise tummy time and floor play. Get on the floor and crawl yourself — babies imitate. Reduce time in seats, bouncers, and walkers, which provide little incentive to develop independent locomotion. Place interesting objects just out of reach to create motivation to move. Remove barriers (lower rugs that impede movement, clear floor space).
