The Short Answer
Most babies begin crawling between 7 and 10 months of age, with the average around 9 months. However, crawling is not a universal milestone — some babies skip crawling entirely and move straight to pulling up and walking, which is developmentally normal.
Stages Leading Up to Crawling
Crawling does not happen overnight. It builds on a sequence of motor skills:
1. Tummy Time (0–6 Months)
Daily tummy time strengthens the neck, shoulder, arm, and core muscles needed for crawling. The AAP recommends starting tummy time from birth, working up to 30 minutes per day by 3–4 months.
2. Rolling (4–6 Months)
Rolling front-to-back and back-to-front builds the coordination and body awareness that prepares babies for moving through space.
3. Sitting Independently (6–8 Months)
Once a baby can sit without support, they have developed enough trunk strength to support themselves in a crawling position.
4. Rocking on Hands and Knees (6–9 Months)
A baby who rocks back and forth on all fours is figuring out weight distribution and timing — the neural groundwork for forward movement.
5. Crawling (7–10 Months)
Most babies use cross-pattern crawling (opposite arm and leg moving together), which also promotes bilateral brain development. Some babies use alternative methods first.
Types of Crawling
All of these are normal:
- Classic crawling: Opposite hand and knee move together
- Army/commando crawling: Belly on the floor, pulling with arms
- Bear crawling: Arms and legs straight, bottom in the air
- Bottom shuffling: Sitting upright and shuffling on the bottom
- Rolling: Some babies roll to their destination instead of crawling
Signs Your Baby Is Getting Ready to Crawl
- Pushes up onto hands and knees from tummy time
- Rocks back and forth on all fours
- Reaches forward while seated, shifting weight onto hands
- Starts moving backwards before they can go forward (very common)
- Explores surroundings with greater urgency
How to Encourage Crawling
- More tummy time — the single most important preparation for crawling
- Place toys just out of reach during tummy time to motivate reaching and moving
- Get down on the floor with your baby and model crawling
- Reduce time in bouncers and swings — floor play builds the muscles that containers cannot
- Use a crawling tunnel or low obstacle for babies who are close but not yet moving
When to Talk to Your Doctor
Contact your paediatrician if your baby:
- Is not sitting independently by 9 months
- Is not showing any attempt at mobility by 12 months (rolling, crawling, scooting, or pulling up)
- Has asymmetric movement (only using one side of the body)
- Has stiff, rigid, or floppy muscle tone that seems abnormal
- Loses skills they previously had (regression always warrants evaluation)
The CDC's "Learn the Signs. Act Early." programme emphasises that early referral to a developmental paediatrician or physiotherapist leads to better outcomes if delays are present.
Do All Babies Need to Crawl?
No. Research from the American Academy of Pediatrics confirms that crawling is not a required milestone. Many healthy babies bottom-shuffle or pull to standing and never crawl, and go on to walk and develop normally. What matters is that babies are moving and exploring — not the specific method they use.
