Your baby's physical development is unique, and concerns about is not walking at 18 months, here is what you need to know.
The short answer
While most babies walk by 15 months, the WHO considers walking alone as normal up to 17.6 months. If your baby is not walking at 18 months, your pediatrician will want to evaluate them, but many late walkers have no underlying issues. Babies who were premature, who are bottom shufflers, or who are more cautious temperamentally may walk later.
Key takeaways
- While most babies walk by 15 months, the WHO considers walking alone as normal up to 17.6 months. If your baby is not walking at 18 months, your pediatrician will want to evaluate them, but many late walkers have no underlying issues. Babies who were premature, who are bottom shufflers, or who are more cautious temperamentally may walk later.
- Usually normal when: Your baby is cruising, standing independently, and may take a few steps with hands held.
- Call your doctor if: Your baby was walking and has stopped or lost motor skills.
- Varies by age — see the age-by-age breakdown below
“Supervised tummy time is recommended daily from the time the baby comes home from the hospital to help prevent flat head syndrome and to strengthen neck and shoulder muscles.”

What Parents Should Know
According to WHO, AAP, CDC guidelines, while most babies walk by 15 months, the WHO considers walking alone as normal up to 17.6 months. If your baby is not walking at 18 months, your pediatrician will want to evaluate them, but many late walkers have no underlying issues. Babies who were premature, who are bottom shufflers, or who are more cautious temperamentally may walk later. At 15-16 months, about 90% of babies walk independently by 15 months, but the remaining 10% are still perfectly normal. If your baby is cruising confidently, standing independently, and perhaps taking a few steps, walking is likely imminent. Some babies simply take more time to build confidence. Mention it at your well visit, but this is often within the normal range. It is generally considered normal when your baby is cruising, standing independently, and may take a few steps with hands held. However, you should contact your pediatrician promptly if your baby was walking and has stopped or lost motor skills.
Normal vs. Concerning
By Age
What to expect by age
15-16 months
About 90% of babies walk independently by 15 months, but the remaining 10% are still perfectly normal. If your baby is cruising confidently, standing independently, and perhaps taking a few steps, walking is likely imminent. Some babies simply take more time to build confidence. Mention it at your well visit, but this is often within the normal range.
16-18 months
If your baby is approaching 18 months without walking, your pediatrician should evaluate their motor development. However, many babies who walk at 16-18 months have no developmental concerns at all. Your doctor will check muscle tone, joint flexibility, and overall strength. If everything looks normal, they may recommend a short course of physical therapy to help build confidence.
18-21 months
Walking after 18 months warrants medical evaluation. Your pediatrician may refer to a developmental pediatrician or physical therapist. Common treatable causes include hypermobility (very flexible joints), mild low muscle tone, or simply being a cautious child. Physical therapy can make a big difference at this stage.
21-24 months
If your child is still not walking by 21 months, a thorough developmental evaluation is important. While some children are simply very late walkers with no underlying cause, this level of delay may indicate conditions that benefit from early intervention, such as hypotonia, developmental coordination disorder, or other treatable conditions.
What to Tell Your Pediatrician
- Describe when you first noticed is not walking at 18 months and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your baby is 15 months old and not yet taking independent steps.
- Mention if your baby is not cruising along furniture by 12 months.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your baby is cruising, standing independently, and may take a few steps with hands held.
- Your baby was premature - use adjusted age, which may shift walking by several months.
- Your baby was a bottom shuffler, as bum shufflers commonly walk later (15-21 months).
- Your baby seems cautious and careful rather than physically unable to walk.
- Your baby is 15 months old and not yet taking independent steps.
- Your baby is not cruising along furniture by 12 months.
- Your baby seems to have weak legs, floppy muscle tone, or very stiff legs.
- There is a family history of neuromuscular conditions.
- Your baby was walking and has stopped or lost motor skills.
- Your baby cannot stand with support, has significant weakness, or cannot bear any weight on their legs.
What You Can Do at Home
- Keep track of when you notice is not walking at 18 months — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby is cruising, standing independently, and may take a few steps with hands held — this is generally within the range of normal.
- At 15-16 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Provide plenty of supervised floor time and tummy time to support your baby's physical development.
- While monitoring at home, seek immediate care if your baby was walking and has stopped or lost motor skills.
Related Conditions
My Baby Isn't Walking
The normal range for first independent steps is huge - anywhere from 9 to 18 months, and all of it is considered typical development. Many parents feel pressure when they see other babies walking early, but a baby who walks at 15 months is just as healthy as one who walks at 10 months.
My Baby Cruises but Won't Let Go and Walk
The time between cruising and independent walking varies enormously, from a few days to several months. Most babies cruise for 1-3 months before walking independently. Cruising shows your baby has the strength and balance foundations for walking - they just need to build the confidence to let go. This transition period is completely normal.
Low Muscle Tone (Hypotonia)
Low muscle tone means your baby's muscles feel less firm or their body feels "floppy" when you hold them. While it can sometimes indicate an underlying condition, many babies with mildly low tone do very well with support and strengthening activities.

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.
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.
