Your baby is about to reach one of the most exciting gross motor development milestones of his or her life: crawling, so you’re most likely watching for signs and wondering by which month they will be moving on their own.
When babies start crawling, they’re not just moving forward—they are strengthening their core muscles, building hand-knee coordination, and exploring the world with confidence and curiosity.
This guide explains when babies may start crawling, the different styles, the most common stages leading up to it, how to encourage crawling safely, and what to do if your baby seems delayed or skips it altogether.

When Do Babies Start Crawling?
Your baby may start crawling between 6 and 10 months, though this age range may vary widely, and one of the first signs is rocking on hands and knees. Some babies do this as early as five months, while others may not start until 11 months or skip it entirely.
What’s normal?
- Early crawlers: 5–6 months
- Typical crawlers: 7–10 months
- Later crawlers: 10–11 months
- Skippers: go straight to pulling up or walking
Every baby’s timeline is different, and variation in crawling milestones is usually normal. But, for your reference, here’s a timeline that’s most common for babies:
Stage 1 (3–5 months): Tummy time & early movements
At this stage, babies spend a lot of time on their tummies, exploring the world from a new angle. Using their hands and arms, they begin to push up and lift their belly off the floor, building the strength they need for future movements. Regular tummy time is key to developing these early skills.
Stage 2 (6–7 months): Rocking and rolling
Around six months, babies start to rock back and forth on the floor, learning to roll from their back to tummy and vice versa. These movements are not only fun but also help them understand balance and body control in a safe environment.
Stage 3 (8–10 months): Hands-and-knees crawl
By eight months, babies are ready to crawl! Using their hands and knees, they begin to move across the floor, exploring their surroundings with growing confidence. This hands-and-knees crawling strengthens muscles and coordination, setting the stage for walking.
Signs Your Baby May Start Crawling Soon
- Rocking back and forth on the belly, then on hands and arms, and knees
- Pivoting in circles during tummy time
- Pushing backward instead of forward
- Reaching across the body (cross-lateral movements)
- Getting into a plank or bear pose
- Trying to move from sitting to all-fours
These early movement signs help build the strength and hand-knee coordination your baby needs for crawling.
Different Crawling Styles
Babies may use one crawling style or switch between several. All are normal:
1. Classic Hands-and-Knees Crawling
Alternating hand and knee, building cross-body coordination.
2. Commando/Army Crawling
Baby moves forward on their belly, pulling with their arms while the lower body drags behind—common in early crawlers.
3. Bear Crawling
Baby crawls on hands and feet with knees lifted off the floor—great for strength.
4. Crab Crawling
Crab crawlers typically push off with one arm more than the other while using the opposite arm to help pull their body sideways or backward. Their arms do most of the lifting and shifting because their legs aren’t doing the usual forward-and-back crawl pattern yet.
5. Bum-Shuffling/Scooting
Baby moves while sitting—less pressure on wrists and knees.
Each method strengthens different muscle groups and supports overall development.
Developmental Stages Before Crawling
Crawling doesn’t happen overnight. It’s built on several important milestones:
1. Tummy Time (From Birth)
Essential for developing neck, shoulder, back, arm, and belly strength.
It’s simple: the more floor time your baby has under his or her belt, the earlier they will crawl.
2. Head and Neck Control (Around 3–4 Months)
Babies gain the stability needed to lift their chest off the ground.
3. Rolling (4–6 Months)
Rolling strengthens the core, helping babies shift weight side-to-side.
4. Sitting Independently (6–8 Months)
Once babies sit confidently, they start leaning forward, reaching, and preparing to get onto their hands and knees.
5. Rocking & Weight Shifting
A key pre-crawling stage where babies rock on all fours and practice balancing.
These stages help babies develop the core strength, hand-knee positioning, and coordination needed for hands-and-knees crawling.
Factors That Affect Crawling Milestones
Babies may crawl earlier or later depending on:
- Genetics: Family patterns may influence timing.
- Floor Time: More time on the floor → stronger muscles → earlier crawling.
- Environment: Safe, open spaces encourage movement.
- Prematurity: Preemies may crawl later than full-term babies.
- Temperament: Some babies prefer sitting or pulling up instead of crawling.
- Sleep Patterns: Babies who get enough restful sleep often have better energy and muscle recovery for movement.
Remember: variability is normal.
When Crawling Looks Different: When to Watch vs When to Worry
Not all babies crawl the same way—or on the same timeline—and that variation is usually normal. Some babies start with belly or commando crawling, others move backward before going forward, and some skip crawling altogether and go straight to pulling up or walking. These differences are part of typical development and often reflect individual strength, coordination, and temperament rather than a problem.
Normal crawling variations to watch (not worry about)
Many babies:
- Prefer belly crawling for weeks before lifting fully onto hands and knees
- Use one arm or leg more strongly at first
- Rock back and forth without moving forward for a while
- Crawl backward before figuring out forward movement
- Take breaks from crawling during growth spurts, illness, or sleep changes
These patterns still help build arm, belly, and core strength and support brain development.
When it may be worth talking to a doctor
While variation is common, consider checking in with a pediatrician if:
- Your baby avoids floor time entirely or seems uncomfortable bearing weight on arms or knees
- There is very limited movement on one side of the body
- Muscle stiffness or extreme floppiness is noticeable
- Crawling attempts don’t progress at all over several months
A doctor can help determine whether additional support or simple exercises are needed.
The big picture
Crawling is just one milestone in a much larger developmental process. Babies develop skills in bursts, not straight lines, and progress often looks uneven before it clicks together. This information is meant to guide and reassure—not diagnose.
How to Encourage Crawling
You can help your baby build crawling skills through play and positioning.
1. Create a Safe Crawling Space
- Use a soft mat or carpeted area.
- Remove small objects and hazards.
- Ensure furniture is stable and corners are covered.
A spacious environment motivates movement.
2. Use Interactive Floor Play
- Get on the floor with your baby.
- Encourage reaching and weight-shifting.
- Place yourself slightly out of reach to motivate them.
3. Motivate with Toys
- Use colorful, noisy, or rolling toys.
- Place toys ahead of your baby during tummy time.
- Try tunnels or pillows to boost curiosity.
Exercises to Build Crawling Skills
Add exercises that include hand, knee, and coordination signals:
Reaching Activities
Place toys diagonally to encourage cross-body reaching.
Supported All-Fours Position
Gently help your baby onto hands and knees, then show how to rock back and forth.
Leg Pushes
Let your baby push off your hands to learn forward motion.
Obstacle Play
Soft pillows help babies practice balance and strength.
These activities build core stability and coordination needed for crawling.
Final Thoughts
Crawling is a major milestone that supports strength, balance, and brain development. With enough floor time, a safe space, restorative sleep, and fun play, your baby can explore at their own pace.
Celebrate every wiggle, rock, and shuffle—each movement is a building block toward confident crawling.
