Most children start jumping with both feet off the ground around age 2, with the skill becoming more consistent by 30 months (2.5 years). Like all motor milestones, there’s a range of normal, and the type of jump matters. A toddler bouncing in place develops months before a preschooler hopping on one foot.
When the First Jumps Happen
Around age 2, toddlers begin attempting their first real jumps, getting both feet off the ground at the same time. These early jumps are small and wobbly. Evidence-based milestone guidelines place “jumps off the ground with both feet” at 30 months as the age by which most children can do it reliably. Before that point, you’ll often see a toddler bend their knees and push up without actually leaving the floor, or lift one foot while the other stays planted.
Jumping down from a low surface, like a bottom stair or a curb, tends to emerge around the same window. According to Nationwide Children’s Hospital, jumping and climbing skills begin to appear around age 2, and as the year progresses children start jumping forward and down from low surfaces with increasing confidence.
How Jumping Skills Progress by Age
Jumping isn’t one skill. It’s a whole sequence that unfolds over several years:
- 18 to 24 months: Bouncing in place with knees bending, feet may not fully leave the ground. Some early attempts at stepping off low surfaces.
- 24 to 30 months: First true two-footed jumps in place. Jumping down from a low step. Landing is often stiff and unsteady.
- 30 to 36 months: Jumping forward a short distance. More controlled landings. Starting to jump over small objects on the ground.
- 3 to 4 years: Hopping on one foot a few times. Jumping further distances. Better arm coordination during the jump.
- 4 to 5 years: Hopping on one foot more consistently, though hopping equally well on each leg is still difficult for many preschoolers. Jumping becomes part of running and play naturally.
One-legged hopping is the hardest variation. Research on preschool-aged children confirms that jumping on one leg and switching the supporting leg is the most difficult jumping task, and it’s common for children in this age range to perform unevenly between their right and left sides.
Why Jumping Is Harder Than It Looks
Jumping requires a surprising amount of coordination for a small body. It demands leg strength, balance, and the ability to coordinate upper and lower limbs at the same time. When a child jumps, their muscles need both explosive power to push off and elastic flexibility to absorb the landing. That’s a lot to coordinate when you’ve only been walking for a few months.
This is why jumping develops after walking and running. Walking requires alternating legs. Jumping requires both legs to fire together while the arms swing in sync to generate momentum. The brain has to plan the takeoff, the airborne moment, and the landing as one continuous movement. Toddlers who are still refining their balance on two feet simply don’t have the foundation yet.
When a Delay May Need Attention
There’s a wide window of normal for jumping, so a 2-year-old who isn’t jumping yet isn’t automatically behind. Pediatric physical therapists generally become concerned if a child is making no attempts to jump by 2.5 to 3 years old. “No attempts” is the key phrase here. A child who tries but can’t quite get airborne is in a different category than one who shows no interest or effort at all.
Around 2.5 years, if your child is still struggling with jumping and also shows signs like difficulty with stairs, frequent tripping, stiffness in the legs, or trouble squatting down and standing back up, it may be worth having a physical therapist evaluate their alignment, strength, and balance. These assessments are straightforward and can identify whether a child just needs more time or would benefit from targeted strengthening exercises.
Helping Your Child Practice
You don’t need special equipment to encourage jumping. Toddlers naturally want to jump once they see other kids doing it, and most of the “practice” happens through play. Jumping off a bottom stair step (with you spotting), bouncing on a soft surface, or playing games where you jump together all build the leg strength and coordination your child needs. Trampolines designed for toddlers, the small ones with a handlebar, are popular because the bouncy surface makes it easier to get airborne, which builds confidence.
Avoid pushing a child to jump before they’re ready. If their legs aren’t strong enough or their balance isn’t there yet, forcing the movement can lead to frustration or awkward landing habits. Most kids get there on their own timeline, and the best thing you can do is give them plenty of opportunities to climb, squat, and move freely throughout the day. Those activities build the same muscles that jumping eventually requires.
