The safest way to teach a baby to go down stairs is feet-first on their belly, facing away from the bottom. Most babies are physically ready to start learning this between 15 and 18 months, though going down is harder than going up and takes longer to master. Here’s how to build the skill in stages, from first attempts through walking down independently.
Why Going Down Is Harder Than Going Up
Babies figure out how to crawl up stairs surprisingly fast. The motion is intuitive: they can see where they’re going, and gravity works in their favor for grip. Going down is a different challenge entirely. It requires a child to trust a surface they can’t see, coordinate their legs behind them, and control their speed against gravity rather than with it. Stair falls account for roughly 12% of all fall injuries in toddlers aged one to two, making this one of the higher-risk motor skills your child will learn.
The typical progression looks like this:
- 15 to 18 months: Crawling up stairs and creeping down backward on the belly, with close supervision
- 19 to 21 months: Walking up stairs holding a railing, placing both feet on each step before moving to the next
- Around 3 years: Walking up with alternating feet, walking down with both feet on each step
- Around 4 years: Walking up and down with alternating feet, no railing needed
These are averages. Some children hit them earlier, some later. The key readiness sign isn’t age but ability: your child should be a confident crawler and able to pull to standing before you introduce stair practice.
The Belly-Down Method
This is the technique recommended most widely by pediatric therapists. Your baby lies on their stomach, feet pointed toward the bottom of the stairs, and slides down one step at a time. Their low center of gravity and full-body contact with the stairs make a fall nearly impossible if you’re spotting them.
Start with just two or three carpeted steps if you have them. Place your baby on their belly near the top of this short section, with their feet hanging over the edge of the first step down. Gently guide their feet to the next step so they feel the surface beneath them. Most babies will instinctively push back once they understand there’s something solid to land on. Stay right behind them (one step below) so you can catch them if they try to roll or turn around.
The hardest part for most babies is the initial turn. They arrive at the top of the stairs facing forward and need to flip onto their belly and reverse direction. Practice this rotation on flat ground first. Get your baby into a crawling position, then lure them to turn around using a toy or your voice behind them. Once they can pivot 180 degrees on a flat surface, they’ll transfer that skill to the top of the stairs more easily.
Repeat short sessions of two to three minutes a few times a day rather than one long practice. Young toddlers lose focus quickly, and fatigue increases the chance of a slip.
The Bottom Scoot
Some babies prefer sitting upright and scooting down on their bottom, one step at a time. This works well for children who resist lying on their belly or who have already started walking and find the crawling position unnatural. Either method is safe. Choose whichever your child takes to more naturally.
For the bottom scoot, sit your child on the top step with their legs dangling over the edge. Hold their hands or hips and help them slide their bottom forward and down to the next step. They’ll land with a small bump. After a few guided repetitions, most toddlers start initiating the forward slide on their own. The advantage of this method is that your child can see the stairs below them. The disadvantage is a slightly higher center of gravity than the belly-down approach, so stay within arm’s reach.
Moving to Upright Descent
Once your child is walking confidently on flat ground, typically between 19 and 24 months, they’ll start wanting to walk down stairs like you do. This transition takes months and passes through several stages.
The first upright method most toddlers use is stepping down with both feet landing on each step before moving to the next. They’ll need to hold a railing with one hand and your hand with the other. If your railing is too high for them to reach, you become the railing. Stand one step below your child, facing them, and let them grip your fingers as they step down. Keep your hold loose enough that they’re doing the balance work, not you.
If your child struggles with stepping down while facing forward, try having them face sideways. They hold the railing with both hands, step the lower foot down to the next step, then bring the higher foot to meet it. Children’s Hospital of Philadelphia recommends this sideways approach as a bridge skill. It lets kids keep both hands on something stable while they build the leg strength and confidence to face forward.
Alternating feet on stairs, the way adults walk them, doesn’t typically develop until around age three going up and closer to four going down. Don’t rush it. The two-feet-per-step method is perfectly functional and much safer for a toddler’s coordination level.
Making Your Stairs Safer for Practice
Carpeted stairs provide more grip and a softer landing than hardwood or tile. If your stairs are bare, consider adding adhesive tread strips to the edges of each step. Socks are slippery on most surfaces, so have your child practice barefoot or in shoes with rubber soles.
Keep stairs clear of toys, blankets, and anything else that could slide underfoot. Good lighting matters more than you’d expect. A dim stairwell makes it harder for a toddler to judge where one step ends and the next begins.
For the times you aren’t actively practicing, stair gates remain essential. Hardware-mounted gates, which screw into the wall, are the standard for the top of stairs because they can’t be pushed out by a child leaning on them. Pressure-mounted gates (the kind that wedge in like a curtain rod) are fine at the bottom of stairs but aren’t secure enough for the top. Federal safety standards specifically flag incorrect installation of pressure-mounted gates as an ongoing injury risk, so if you use one, check that it’s snug enough that it can’t be dislodged with a firm push.
Common Mistakes That Slow Progress
Holding your child’s hand from above while they face forward is the instinctive thing most parents do, but it teaches a bad habit. Your child learns to rely on being pulled upward rather than controlling their own descent. When you eventually let go, they don’t have the balance skills to manage alone. Spotting from below, or holding hands at the child’s level, keeps the balance challenge where it belongs.
Another common issue is practicing only going down. Children build stair confidence in both directions simultaneously. Let them crawl up a few steps and then turn around and come back down. The up-down cycle reinforces the turning skill, which is the most dangerous moment since it’s the point where a child is briefly facing the wrong way at the top of the stairs.
Finally, avoid carrying your child down the stairs during the learning phase whenever it’s practical to let them do it themselves. Falls while being carried by an adult are one of the more common sources of serious pediatric fall injuries because the child falls from a greater height with less ability to brace. Letting your toddler descend under their own power, with you spotting, is often safer than carrying them, and it builds the skill faster.
