Baby's Stepping Reflex Is Absent

Editorially reviewed | Sources: AAP, NIH, CDC|Updated June 2026

The short answer

The stepping (or walking) reflex is a primitive reflex present at birth where a newborn makes stepping motions when held upright with feet touching a flat surface. This reflex normally disappears by about 2 months of age. An absent stepping reflex at birth may indicate prematurity, neurological concerns, or breech positioning effects. However, this reflex is variable and can be difficult to elicit in some healthy newborns. Your pediatrician evaluates reflexes as part of the newborn exam.

Parents everywhere have the same worry. You are doing the right thing by looking into it.

By Age

What to expect by age

0-2 months

The stepping reflex is normally present in full-term newborns and is tested by holding the baby upright with feet touching a surface - the baby should make alternating stepping motions. This reflex can be variable in strength and is sometimes difficult to elicit in sleepy or recently fed babies. Premature babies may have a weaker stepping reflex. The reflex is one of many primitive reflexes assessed during newborn examinations. An isolated absent stepping reflex, if all other reflexes and neurological exams are normal, may not be clinically significant.

2-4 months

The stepping reflex naturally disappears around 2 months of age as the baby's legs become heavier relative to their muscle strength and as the brain develops more voluntary movement control. The absence of this reflex after 2 months is completely normal and expected. It is not related to when your baby will eventually learn to walk. The stepping reflex reappears later as a voluntary behavior when babies begin pulling to stand and cruising, typically around 8-12 months.

4-12 months

The stepping reflex should be gone by this age. Your baby is now developing voluntary leg movements: kicking, pushing off surfaces, and eventually pulling to stand. The absence of the primitive stepping reflex at this age is normal. If your baby is not bearing weight on their legs when held upright by 6-8 months, or not developing other gross motor skills on track, discuss this with your pediatrician as a separate concern from the stepping reflex.

What Should You Do?

When to take action

Probably normal when...
  • Your newborn has a variable stepping reflex - sometimes present and sometimes hard to elicit.
  • The stepping reflex has disappeared by 2-3 months of age.
  • Your premature baby has a weaker stepping reflex that was present at birth.
Mention at your next visit when...
  • Your full-term newborn has no stepping reflex along with other weak or absent reflexes.
  • Your baby has asymmetric stepping - one leg steps but the other does not.
  • Your baby has an absent stepping reflex combined with very stiff or very floppy legs.
Act now when...
  • Multiple reflexes are absent in your newborn along with poor muscle tone, difficulty feeding, or lethargy.
  • Your baby has no movement in one or both legs at any age.
  • Your newborn has absent reflexes with seizures or extreme irritability.

Trust your instincts. If something feels wrong, reach out to your pediatrician.

Worrying about your baby means you care. That is a good thing.

Baby's Primitive Reflexes Not Integrating

Primitive reflexes are automatic movement patterns that babies are born with, such as the Moro (startle), grasp, and rooting reflexes. These normally integrate (fade) during the first year as the brain matures. If primitive reflexes persist well beyond their expected timeline, it may indicate a neurological concern that should be evaluated by your pediatrician.

Baby's Rooting Reflex Is Absent

The rooting reflex causes a newborn to turn their head and open their mouth when their cheek or lip is stroked, helping them find the breast or bottle. This reflex is normally present at birth and gradually fades by 3-4 months as feeding becomes more voluntary. An absent or very weak rooting reflex in a newborn may indicate prematurity, neurological concerns, or simply that the baby was recently fed. Mention an absent rooting reflex to your pediatrician for evaluation.

My Baby Isn't Standing Independently

Independent standing - letting go and balancing without holding anything - typically happens between 9 and 14 months, with many babies not mastering it until around 12 months. Standing independently requires tremendous balance and confidence, and it's one of those skills that often clicks suddenly after weeks of almost-but-not-quite moments.

My Baby Isn't Kicking Their Legs

Most babies begin kicking their legs actively within the first few weeks of life, and leg kicking becomes more vigorous and coordinated by 2-3 months. If your baby is not kicking their legs or kicks very infrequently, it could be related to muscle tone, prematurity, or other factors. Your pediatrician can help determine if evaluation is needed.

Should I Use Adjusted Age for My Preemie's Milestones?

Yes — for premature babies, developmental milestones should be assessed using adjusted (corrected) age, not chronological age, until at least 2 years of age. Adjusted age is calculated by subtracting the number of weeks your baby was born early from their actual age. For example, a 6-month-old born 2 months early would have an adjusted age of 4 months, and should be assessed against 4-month milestones. Most pediatricians use adjusted age for developmental assessment through age 2-3, and for growth charts through age 2.

Baby-Proofing a Small Apartment

Baby-proofing a small apartment is absolutely possible and focuses on the same key safety principles as any home: securing furniture to walls, covering outlets, locking cabinets with hazardous materials, and ensuring safe sleep spaces. Small spaces actually have an advantage - there is less area to monitor. Focus on eliminating the most dangerous hazards first: falls, poisoning, choking, and burns.
