My Baby's Movements Seem Uncoordinated
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.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
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 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.

Related Physical Concerns
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.
My Baby Still Has the Fencing Reflex (Persistent ATNR)
The asymmetric tonic neck reflex (ATNR, also called the fencing reflex) causes your baby to extend the arm on the side they are looking toward. It should integrate between 4-6 months. If the ATNR persists strongly beyond 6 months, it can interfere with bringing hands to midline, bilateral hand use, and rolling. Evaluation is recommended.
Signs of Ataxia in Babies and Toddlers
Ataxia refers to wobbly, uncoordinated movements that result from problems with the cerebellum (the brain's coordination center). Signs include an unsteady, wide-based gait, difficulty with precise hand movements, and intention tremor (shaking that worsens when reaching for something). If you notice these signs, evaluation by a pediatric neurologist is important.
