Your baby's physical development is unique, and concerns about movements seem uncoordinated, here is what you need to know.
The short answer
All babies start out with uncoordinated movements - it takes time for the brain and muscles to learn to work together smoothly. What matters most is that your baby is making progress over time. If movements are becoming smoother and more purposeful as your baby grows, they're on the right track, even if they're a bit clumsier than other babies their age.
Key takeaways
- All babies start out with uncoordinated movements - it takes time for the brain and muscles to learn to work together smoothly. What matters most is that your baby is making progress over time. If movements are becoming smoother and more purposeful as your baby grows, they're on the right track, even if they're a bit clumsier than other babies their age.
- Usually normal when: Your baby is under 4 months and has jerky, uncontrolled movements - this is expected as their nervous system develops.
- Call your doctor if: Your baby was developing normally and suddenly became much more uncoordinated or lost skills they previously had - regression is always urgent.
- 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 CDC, AAP, Zero to Three guidelines, all babies start out with uncoordinated movements - it takes time for the brain and muscles to learn to work together smoothly. What matters most is that your baby is making progress over time. If movements are becoming smoother and more purposeful as your baby grows, they're on the right track, even if they're a bit clumsier than other babies their age. At 0-3 months, uncoordinated, almost random-looking movements are completely normal at this age. Your baby is just learning that they have arms and legs, let alone how to control them. You might see lots of flailing, jerky motions, and accidental face-smacking. This is all expected. Over these three months, you should start to see more purposeful movements emerge - reaching toward faces, bringing hands together, smoother head turning. It is generally considered normal when your baby is under 4 months and has jerky, uncontrolled movements - this is expected as their nervous system develops. However, you should contact your pediatrician promptly if your baby was developing normally and suddenly became much more uncoordinated or lost skills they previously had - regression is always urgent.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Uncoordinated, almost random-looking movements are completely normal at this age. Your baby is just learning that they have arms and legs, let alone how to control them. You might see lots of flailing, jerky motions, and accidental face-smacking. This is all expected. Over these three months, you should start to see more purposeful movements emerge - reaching toward faces, bringing hands together, smoother head turning.
4-6 months
Your baby should be gaining a lot more control now - reaching for objects with both hands, bringing toys to their mouth, rolling from tummy to back. Movements should look much more deliberate and less jerky than they did at birth. If your baby's movements still seem completely random and uncontrolled, or if one side of the body moves very differently from the other, mention it to your pediatrician.
7-12 months
By this age, most movements should be fairly coordinated - your baby can sit without support, transfer toys from hand to hand, crawl or scoot, and maybe pull to stand. Some clumsiness is normal (babies bonk their heads a lot when learning to sit), but overall you should see smooth, controlled movement. If your baby still seems very uncoordinated compared to peers, struggles with basic skills like sitting or picking up objects, or uses one side of the body much more than the other, talk to your doctor.
12+ months
Toddlers learning to walk are naturally clumsy and will fall often. But their arm movements should be fairly smooth, they should be able to pick up small objects with thumb and finger, and they should be making steady progress with walking and climbing. Persistent, significant clumsiness that interferes with play and exploration may benefit from evaluation by a pediatric physical or occupational therapist.
What to Tell Your Pediatrician
- Describe when you first noticed movements seem uncoordinated 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 over 6 months and movements still seem completely random and uncontrolled, with no clear progress toward purposeful reaching or grasping.
- Mention if one side of your baby's body is much more coordinated than the other, or your baby always uses one hand and ignores the other.
- 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 under 4 months and has jerky, uncontrolled movements - this is expected as their nervous system develops.
- Your baby's coordination is improving over time, even if they're not as smooth as other babies their age.
- Both sides of your baby's body move equally - even if movements are clumsy, they're symmetric.
- Your baby is meeting major milestones like rolling, sitting, and reaching, even if they look a bit awkward doing it.
- Your baby is over 6 months and movements still seem completely random and uncontrolled, with no clear progress toward purposeful reaching or grasping.
- One side of your baby's body is much more coordinated than the other, or your baby always uses one hand and ignores the other.
- Your baby seems unable to do things that most peers can do, like bringing hands together, transferring toys, or sitting without support.
- Uncoordinated movements are accompanied by other concerns like poor muscle tone, delayed milestones, or lack of eye contact.
- Your baby was developing normally and suddenly became much more uncoordinated or lost skills they previously had - regression is always urgent.
- Uncoordinated movements are accompanied by weakness, difficulty breathing, or your baby seems ill.
- Your baby's movements seem chaotic or out of control, and they can't be calmed or comforted.
What You Can Do at Home
- Keep track of when you notice movements seem uncoordinated — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby is under 4 months and has jerky, uncontrolled movements - this is expected as their nervous system develops — this is generally within the range of normal.
- At 0-3 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 developing normally and suddenly became much more uncoordinated or lost skills they previously had - regression is always urgent.

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.
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.
My Baby Crawls Unevenly
While some variation in crawling patterns is normal, consistently favoring one side or dragging one limb while crawling warrants attention. Babies should use both arms and both legs relatively equally when crawling. Persistent asymmetry could indicate muscle tone differences, hip issues, or neurological concerns that benefit from early evaluation.
