My Baby Is Not Walking at 18 Months
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.

By Age
What to expect by age
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.
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.
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.
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 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.

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.
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 Only Army Crawls
Army crawling (also called commando crawling) is a completely valid and normal way for babies to move. Many babies army crawl for weeks or even months before transitioning to hands-and-knees crawling, and some skip hands-and-knees crawling entirely. What matters is that your baby is independently mobile and exploring their environment.
One Side of My Baby's Body Moves Differently
Babies should generally use both sides of their body equally. If one side consistently moves differently, is weaker, stiffer, or less coordinated, this warrants evaluation. Asymmetric movement can indicate hemiplegia (cerebral palsy affecting one side), brachial plexus injury, or other neurological conditions that benefit from early therapy.
