Physical Development

Toddler Not Jumping

The short answer

Jumping with both feet leaving the ground is a skill that typically develops between 24 and 30 months, though some children do not master it until closer to 3 years old. It requires significant coordination, leg strength, and balance, so it is one of the later gross motor milestones to emerge. Most toddlers who are running and climbing well will develop jumping in their own time.

By Age

What to expect by age

Toddlers at this age are focused on learning to walk, and jumping is not yet expected. They may enjoy bouncing while being held or bouncing on a soft surface like a bed or trampoline with support. This bouncing motion helps build the leg strength and coordination that will eventually be needed for independent jumping. There is no cause for concern about jumping at this age.

Some toddlers begin attempting to jump by crouching down and pushing up, though their feet may not fully leave the ground. Others may step off a low step with one foot, which is a precursor to jumping. Many toddlers at this age are still mastering running and climbing and are not yet ready for jumping. This is all within the normal range.

This is the typical window for jumping to develop. Most children can jump with both feet by around 24 to 30 months, starting with small hops and progressing to jumping over objects and off low surfaces. If your child is 30 months or older and cannot get both feet off the ground at all, it is reasonable to mention this to your pediatrician, especially if they also have difficulty running or climbing.

By age 3, most children can jump well with both feet, jump forward, and jump down from a low step. If your child still cannot jump at all by their third birthday, a gross motor evaluation can help determine whether physical therapy or other support would be beneficial. Some children simply need extra practice, while others may have mild strength or coordination differences that respond well to targeted exercises.

What Should You Do?

When to take action

Probably normal when...
  • Your toddler is under 2 years old and not yet jumping, as this skill typically develops between 24 and 30 months.
  • Your toddler is attempting to jump by crouching and pushing up, but their feet are not yet fully leaving the ground.
  • Your toddler can jump on soft surfaces like a trampoline or bed but struggles on hard floors.
  • Your toddler is walking and running well but has not figured out the coordination for jumping yet.
  • Your toddler jumps with one foot leaving the ground but not both at the same time.
Mention at your next visit when...
  • Your child is over 30 months and makes no attempt to jump or shows no interest in jumping activities.
  • Your child seems to have difficulty with leg strength overall, including trouble climbing stairs, running, or squatting down to pick things up.
Act now when...
  • Your child was previously able to jump and has lost the ability, or is losing other motor skills they previously had.
  • Your child has significant difficulty with all gross motor activities including walking, running, and climbing, along with not jumping.

My Baby Seems to Use One Side More Than the Other

Babies should use both sides of their body fairly equally during the first 18 months of life. While slight preferences can be normal, a consistent pattern of favoring one side - using one arm much more than the other, crawling with one leg dragging, or turning the head predominantly one way - should always be discussed with your pediatrician. Early identification of asymmetry leads to the best outcomes.

My Baby Curls Their Toes

Toe curling is very common in babies and is usually caused by the plantar grasp reflex, which is a normal newborn reflex that causes toes to curl when the sole of the foot is touched. This reflex typically fades by 9-12 months. Occasional toe curling during standing or walking is also normal as babies figure out their balance. Persistent, tight toe curling past 12 months may warrant a mention to your pediatrician.

My Baby Favors One Leg

Babies should use both legs roughly equally when kicking, crawling, and eventually walking. If your baby consistently favors one leg or seems to avoid using the other, it is worth having your pediatrician take a look. The cause is often something simple and treatable, like a minor hip or muscle issue, but early evaluation helps ensure the best outcome.

My Baby Gets Hiccups a Lot

Hiccups are extremely common in babies, especially newborns, and are almost always completely harmless. They happen because your baby's diaphragm is still developing and gets a little jumpy when their tiny stomach fills up or air gets swallowed. Most babies outgrow frequent hiccupping by 6-9 months.

My Baby Has Jerky Movements

Newborns and young babies often have jerky, uncoordinated movements because their nervous systems are still developing. What looks like random flailing is actually your baby learning how their body works. These movements typically become smoother and more controlled by 3-4 months as motor skills mature.

Baby Not Bearing Weight on Arms

Bearing weight on the arms is a gradual skill that develops during the first 6 months. Babies first prop up on their forearms around 2 to 4 months, then progress to pushing up on extended arms by 5 to 6 months. Regular tummy time is the best way to build this strength, even if your baby protests at first.
