Crawling 101: Everything You Need to Know About This Major Milestone
Your baby is getting bigger. They're spending more time on their belly. And you're wondering: when should crawling actually happen? Am I supposed to make it happen? What if they skip it? Is that even a thing?
Let me break down crawling in a way that actually makes sense. (Spoiler: crawling is way more complex and important than most parents realize.)
What Actually Happens During Crawling?
Crawling doesn't just pop up one day. It's the result of months of development building on top of each other. Before crawling, your baby needs:
Shoulder stability. Your baby's shoulders need to be strong and stable enough to support their body weight while they're moving. This starts way earlier—think head control, weight shifting in tummy time, reaching for toys.
Core strength. A strong, mobile core helps your baby balance on hands and knees (or hands and feet if they're army crawling). They need the ability to rotate through their trunk, not just move in straight lines.
Hip mobility and strength. Those hip muscles? Huge for crawling. They help your baby maintain balance and generate power in their legs.
Cross-body coordination. This is when your baby can move their right arm and left leg together (or vice versa) in an organized way. This is called crossing the midline, and it's a big deal for brain development.
Motivation. This one gets overlooked, but it's everything. Your baby needs reasons to crawl. Reasons that matter to them.
When all these pieces come together? Crawling happens. Usually between 6 and 12 months, though that's a really wide range and totally normal.
The Crawling Timeline (And Why It Varies So Much)
Around 5-6 months, your baby might start getting onto their belly intentionally and learning to roll.
By 6-8 months, you might see rocking back and forth on hands and knees. Weight shifting. Maybe some backward movement (yes, crawling backward first is totally normal).
Around 8-10 months, true crawling on hands and knees usually starts to emerge.
What If Your Baby Isn't Crawling Yet?
It is worth paying attention to. If your baby is 9-10+ months and showing little or no interest in mobility, or if they're not building strength in the ways we'd expect, that's worth exploring.
A few things that can slow down crawling:
Too much time in containers. Car seats, bouncers, swings—these are helpful tools, but if your baby spends most of their day in them, they're missing critical floor time where crawling development happens.
Limited tummy time. Your baby needs regular, supervised tummy time to build the strength crawling requires. We're not talking about a position of discomfort. We're talking about a baby who's learning to love being on their belly.
Body tension or restrictions. If your baby has torticollis, tongue tie, or other restrictions, this can impact their ability to move freely. (This is where we come in!)
Low motivation. Some babies are just less interested in moving. They're observers. They need extra reasons to explore. This is personality, not a problem. But it might mean you need to get creative with play setup.
Developmental delays. Sometimes slower-than-typical crawling development is just how that baby develops. Sometimes it's worth an evaluation to understand what's happening.
The key is noticing what's actually happening with your baby, not comparing them to the Baby In Your Mom Group Who Crawled at 6 Months.
How to Support Crawling (Without Forcing It)
Okay, so crawling is important. But how do you actually help your baby get there?
1. Make Tummy Time Happen
Not as torture. As play. Roll your baby onto their belly on a blanket or play mat. Get down there with them. Make funny noises. Roll a toy just out of reach. Sing. Laugh. Model movement (seriously, babies learn by watching). Start small - even 5-10 minutes at a time. Work up from there. If tummy time is a meltdown, something's usually going on (tension, discomfort, overstimulation). We can help troubleshoot this.
2. Create Obstacle Courses
Rolled-up towels. Pillows. Couch cushions. Your own body. These are tools for building strength. Your baby learns to problem-solve. How do I get over this? How do I around this? Their brain is working. Their muscles are engaging.
3. Get Toys Out of Their Reach
This sounds counterintuitive, but put toys just out of reach. On a shelf. Across the room. Make your baby move to get them. Motivation is everything. A toy in their hand? Boring. A toy three feet away? That's a reason to crawl.
What About Skipping Crawling?
Here's the honest answer: some babies skip crawling and move straight to standing and walking. But. Crawling builds neural pathways. Bilateral coordination. Cross-body movement patterns. Full body strength. Integrates reflexes. Builds visual connections. These matter for fine motor skills, academic skills, coordination, even handwriting down the line.
Missing crawling doesn't mean your child is doomed. But it does mean you might want to build crawling-like movements into play later on, like jumping, climbing, rolling, playing games that require coordinated movement.
If your baby is 11+ months with zero crawling movements and zero signs of wanting to crawl, that's worth mentioning to us. We can assess what's happening and figure out if support would help.
Ready to dive deeper into crawling?
We created Crawling Camp specifically for parents like you. It walks through the developmental sequence, gives you play ideas, answers all your "is this normal?" questions, and helps you set up your environment to support crawling naturally.
Or if you'd rather learn with other parents in real time, join us for Curious Crawlers (7-12 months) or Wobbly Walkers (10-18 months) classes in South or North Denver.
And remember: your baby's development isn't a race. It's a journey. We're here to help you feel confident and supported every step of the way.
