Your baby's physical development is unique, and concerns about walks with stiff legs, here is what you need to know.
The short answer
Some stiffness in early walking is normal as babies learn to coordinate their leg muscles. However, persistent stiff-legged walking that does not improve over weeks may indicate increased muscle tone (hypertonia) that should be evaluated. Most babies develop a more fluid walking pattern within a few months of starting to walk.
Key takeaways
- Some stiffness in early walking is normal as babies learn to coordinate their leg muscles. However, persistent stiff-legged walking that does not improve over weeks may indicate increased muscle tone (hypertonia) that should be evaluated. Most babies develop a more fluid walking pattern within a few months of starting to walk.
- Usually normal when: Your baby just started walking and the stiffness is improving week by week.
- Call your doctor if: Your child's walking has become stiffer over time rather than improving.
- 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.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, NIH, CDC guidelines, some stiffness in early walking is normal as babies learn to coordinate their leg muscles. However, persistent stiff-legged walking that does not improve over weeks may indicate increased muscle tone (hypertonia) that should be evaluated. Most babies develop a more fluid walking pattern within a few months of starting to walk. At 10-14 months, new walkers often have a somewhat stiff gait as they learn to coordinate their movements. Bending the knees while walking requires balance and muscle control that develops with practice. If your baby's walking is stiff but improving week by week, this is part of normal learning. Watch for gradual improvement. It is generally considered normal when your baby just started walking and the stiffness is improving week by week. However, you should contact your pediatrician promptly if your child's walking has become stiffer over time rather than improving.
Normal vs. Concerning
By Age
What to expect by age
10-14 months
New walkers often have a somewhat stiff gait as they learn to coordinate their movements. Bending the knees while walking requires balance and muscle control that develops with practice. If your baby's walking is stiff but improving week by week, this is part of normal learning. Watch for gradual improvement.
14-18 months
Your toddler's walking should be becoming more fluid over time. Some stiffness when excited or on new surfaces is normal. If your child consistently walks with very stiff, straight legs and does not seem to be developing a more natural bend, discuss it with your pediatrician. They can check muscle tone and reflexes.
18-24 months
By this age, walking should look fairly fluid with good knee flexion. If your child still walks with noticeably stiff legs, especially if combined with toe walking, scissoring (legs crossing), or difficulty squatting, your pediatrician should evaluate for hypertonia or other neuromuscular concerns.
2-3 years
Persistent stiff-legged walking at this age warrants a thorough evaluation. Your child should be walking, running, and squatting with relatively fluid movements. A pediatric neurologist can assess whether increased muscle tone or other factors are contributing to the pattern.
What to Tell Your Pediatrician
- Describe when you first noticed walks with stiff legs and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your child has been walking for more than 3 months with no improvement in leg stiffness.
- Mention if your child has difficulty bending their knees to squat or climb stairs.
- 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 just started walking and the stiffness is improving week by week.
- Your baby walks stiffly when excited but can walk more normally at other times.
- Your baby can bend their knees to squat, climb, or sit down from standing.
- The stiffness is equal on both sides.
- Your child has been walking for more than 3 months with no improvement in leg stiffness.
- Your child has difficulty bending their knees to squat or climb stairs.
- The stiffness is worse on one side than the other.
- Your child also toe walks or their legs seem to cross when walking.
- Your child's walking has become stiffer over time rather than improving.
- Your child has developed leg stiffness along with other new symptoms like tremors or falls.
What You Can Do at Home
- Keep track of when you notice walks with stiff legs — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby just started walking and the stiffness is improving week by week — this is generally within the range of normal.
- At 10-14 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 child's walking has become stiffer over time rather than improving.
Related Conditions
My Baby Seems Too Stiff (Hypertonia)
Hypertonia means your baby's muscles feel unusually tight or stiff, making it hard to bend or move their limbs. While some stiffness can be normal during certain movements (like when a baby is startled or upset), persistent stiffness at rest warrants evaluation. Early identification and physical therapy can make a significant difference.
My Baby Is Walking on Their Toes
Toe walking is extremely common when babies are first learning to walk and is usually nothing to worry about. Up to 5% of children toe walk at some point, and most outgrow it by age 2-3. It only becomes a concern if it persists past age 2 or if your child seems unable (rather than unwilling) to put their feet flat.
Signs of Spasticity vs Normal Stiffness in Babies
Spasticity is velocity-dependent stiffness, meaning muscles resist fast movement more than slow movement. Normal baby stiffness occurs briefly during excitement or startle and resolves quickly. Spasticity is persistent, may affect one or more limbs, and often worsens with growth. Your pediatrician can perform specific tests to distinguish between normal tone variation and spasticity.

Bottom line
Most cases of walks with stiff legs are normal. Talk to your pediatrician if your child's walking has become stiffer over time rather than improving.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.

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.
