When Will My Baby Crawl, Sit, and Walk? (And What If They Don’t Yet?)

One minute you’re amazed that your baby can hold up their wobbly little head, and the next you’re wondering: when will my baby crawl? Or sit? Or walk? Or maybe attempt to scale the furniture?

It’s completely normal to have questions—and a few worries—about baby developmental milestones. These first-year skills don’t arrive on a strict schedule, and every baby moves at their own pace.

So, let’s look at when sitting, crawling, and walking usually happen, how you can support them, and when it’s worth checking in with a health professional.

💺 When Do Babies Start Sitting Up?

Most babies sit independently between 6 and 8 months.

Before that, they’ll go through stages—sitting with support, toppling over, and slowly building the core strength to stay upright on their own.

How to support it:

  • Give them floor time instead of always using bouncers or seats.

  • Prop them up with pillows and let them practice staying balanced.

  • Engage them in seated sensory activities to build strength and coordination.

🐾 When Will My Baby Crawl?

The big question: when will my baby crawl? Most babies start crawling between 7 and 10 months.

But here’s the important part—not all babies crawl in the same way, or at all. Some bum-shuffle, some roll across the room, and others skip crawling altogether and go straight to standing and walking.

Ways to encourage crawling:

No matter how it looks, the act of learning to move independently helps build coordination, spatial awareness, and confidence.

🚶‍♂️ When Do Babies Start Walking?

Most babies take their first steps between 12 and 15 months, although some start as early as 9 months and others wait until closer to 18 months.

Walking takes time—it’s a mix of muscle strength, balance, and practice.

How to support it:

  • Let your baby go barefoot when possible to help with balance.

  • Offer sturdy furniture to cruise along.

  • Give them space and time to practice, without too much hand-holding.

🧠 What If They’re “Late”?

If your baby isn’t sitting by 9 months, not crawling by 12, or not walking by 18, speak with your health visitor or GP. It might just be their individual pace, but it’s always okay to ask for guidance.

Remember:

  • Premature babies often meet milestones later.

  • There’s a wide range of normal.

  • Comparing your baby to others adds unnecessary stress.

What We See in Baby Classes

At Adventure Babies sensory storytelling classes, we see a bit of everything. Some babies sit and take it all in. Some crawl straight across the room to explore. Others observe quietly or lie back and relax.

Every one of them is learning. Every one of them is developing in their own way.

Final Thought

If you’ve been asking, “When will my baby crawl?”—you’re not alone, and there’s no need to panic. Babies reach physical milestones on their own timelines.

They’re growing, adapting, and learning every day. As long as they’re moving forward (literally or figuratively), they’re doing just fine.
