One minute I was folding laundry, the next I found my baby halfway up the stairs, giggling like it was his big break. It got me wondering — when do babies start climbing stairs? As a parent and someone who’s talked to pediatric therapists and other moms, I’ve learned this stair-climbing milestone is about more than just movement — it’s a sign of growing courage and coordination. In this article, we’ll walk through the typical age ranges, what to expect, how to teach it safely, and even answer questions like “Is it normal for a 7 month old to climb stairs?” or “When should a baby learn to go down stairs?” Stick with me to find out what’s normal, what’s not, and how to support your little climber every step of the way.
In this guide, I’ll walk you through everything you need to know: from when this milestone typically begins, how to know your baby’s ready, what steps (literally!) to take to support them, and when to seek expert help. Let’s get into it.
What Is Considered Stair Climbing for Babies?
So, what exactly counts as “climbing stairs” for babies? It doesn’t mean walking up the stairs just yet. Early on, babies typically crawl up stairs on all fours — hands and knees working together in a coordinated motion. And yes, climbing stairs is a milestone — one that blends strength, balance, coordination, and a little courage.
This skill is more than just cute. It shows us how your baby’s motor planning, muscles, and even decision-making are developing. It’s a big step (pun intended!) in gaining independence and mobility.
When Do Babies Start Climbing Stairs?
Let’s answer your main question directly: Most babies start climbing stairs between 9 and 13 months. Some may try as early as 7 months, especially if they’re strong crawlers or extra curious.
Is it normal for a 7-month-old to climb stairs? While uncommon, it can happen — especially if the baby has already mastered crawling and has lots of energy. Just keep in mind, early climbing doesn’t mean they’re ahead in everything. All babies develop differently.
Here’s a quick breakdown of what you can expect by age:
- 7–9 months: Signs of readiness like pulling to stand, crawling quickly, and trying to climb onto low furniture.
- 9–12 months: Most babies begin to crawl up a few stairs, usually needing supervision.
- 12–15 months: Climbing becomes more confident; they may try to stand while climbing.
- 18+ months: Some start walking up stairs with support (like holding your hand or a railing).
Remember, climbing up often comes much earlier than climbing down — and that’s totally normal.
Signs Your Baby Is Ready to Climb Stairs
How do you know it’s time to babyproof those steps? Look out for:
- Strong upper body and arm muscles
- Fast, stable crawling
- Pulling up on furniture or trying to “scale” things
- Constant curiosity about the stairs
Personal Note: I realized my daughter was ready when she tried to climb onto the couch using her toy box. That little boost gave her just enough leverage — and me a mini heart attack.
From First Crawl to Confident Climber
Learning to climb stairs doesn’t happen overnight. Here are the general stages most babies follow:
- Stage 1: Crawling Up with Help
Around 9–12 months, babies start crawling up steps, especially if you’re behind them cheering them on. - Stage 2: Pulling to Stand at Stairs
Around 12–15 months, they’ll use the bottom step as leverage to stand or peek higher. - Stage 3: Walking Up with Support
From 18–24 months, your little one might start using a railing, your hand, or the wall to step up — usually with two feet per step. - Stage 4: Climbing Alone with Alternating Feet
By age 3+, many children can alternate feet going up and down — a sign of strong balance and coordination.
Tip: Record a video of each stage. It’s amazing to look back and see how far they’ve come!
Teaching Stair Climbing Safely
Safety first — always. Here’s how to guide your baby step-by-step:
- Start low: Practice with just 1–2 steps at first.
- Always supervise: Be directly behind them going up, and below them when going down.
- Use gates: Block stair access until they’ve mastered the skill — and even then, never leave them alone.
- Encourage backwards crawling when going down: It’s the safest early method.
- Motivate with toys: Place a favorite toy at the top (or bottom) to inspire them.
Parent Tip: I learned the hard way that turning your back for a second is all it takes. Now I always keep one hand near my daughter’s waist when she’s on the stairs.
When Should a Baby Learn to Go Down Stairs?
Going down is harder — and usually comes later, between 15 and 18 months. This task requires more balance and a good sense of depth perception.
Babies should learn to go down feet first, crawling backwards, before they try stepping.
So, when should a baby learn to go down stairs? Don’t stress if your 15-month-old still avoids it. Support them with guided practice and lots of praise.
Motivation tip: Place a toy or a familiar sibling at the bottom to encourage safe descent.
Red Flags and When to Worry
Most babies reach the stair-climbing milestone in their own time. But here are some signs to keep an eye on:
- No interest in stairs by 16–18 months
- Difficulty crawling, standing, or weight-shifting
- Frequent tripping or imbalance
- Avoids stairs completely even with encouragement
What age should a child climb stairs independently? Most can walk up with support by 18–24 months, and climb alone by 3 years.
If you’re unsure, consider consulting a pediatric physical therapist. They can assess strength, coordination, and provide tailored tips. One mom in our group saw major progress after just two sessions — and her daughter was stair-walking within weeks.
Encouraging Development Through Play
You don’t need fancy equipment to build stair skills. Try these fun, safe ideas:
- Set up mini climbing zones with pillows and low steps
- Use indoor climbing toys or soft gym blocks
- Play “follow the leader” up a few stairs
- Have older siblings model safe climbing
Focus on fun over pressure. Some days they’ll climb like pros, other days they’ll crawl off mid-way to chase the dog — that’s normal.
