Baby Not Holding Head Steady
The short answer
Head control is one of the first major motor milestones, developing gradually over the first 4 months. Most babies can hold their head steady when held upright by 3 to 4 months. Before this, some head wobbling is completely normal. Regular tummy time is the most important activity for building the neck strength needed for steady head control.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-1 month
Newborns have very limited head control and need their head supported at all times when being held. During tummy time, they may briefly lift their head and turn it to one side. Some head lag when being pulled gently from lying to sitting is completely expected. Always support your newborn's head and neck when picking them up and holding them.
1-2 months
Head control begins to improve. During tummy time, your baby can lift their head briefly at about a 45-degree angle. When held upright against your shoulder, they may hold their head up for short periods before it flops to the side. Head control is still inconsistent and your baby still needs support, but you should see gradual improvement week to week.
2-4 months
This is the period when most babies achieve steady head control. By 3 months, many babies can hold their head steady when held in an upright position, and by 4 months, this should be well established. During tummy time, they hold their head up at 90 degrees and look around. If your baby has significant head lag (head falls back when pulled to sitting) at 4 months, discuss this with your pediatrician.
4-6 months
Head control should be well established by now. Your baby should hold their head steady in all positions, including when being held upright, during tummy time, and when being pulled to a sitting position. If your baby still has poor head control at this age, your pediatrician will likely want to evaluate for low muscle tone, neurological concerns, or other factors. Physical therapy can be very helpful in strengthening neck muscles.
What Should You Do?
When to take action
- Your baby is under 3 months and their head wobbles when held upright, as steady head control is still developing.
- Your baby holds their head steady most of the time but occasionally loses control when startled or tired.
- Your premature baby has head control consistent with their adjusted age rather than their birth age.
- Your baby lifts their head well during tummy time but still has some wobble when held in an upright sitting position.
- Your baby's head control improves week to week, even if they are not yet fully steady.
- Your baby is 4 months old and cannot hold their head steady when held upright, or has significant head lag when pulled to sitting.
- Your baby does not lift their head at all during tummy time by 3 months.
- Your baby's head control seems to be getting worse rather than improving over time.
- Your baby had good head control and has suddenly lost it, as this could indicate a serious neurological concern.
- Your baby has no head control at all by 4 months combined with overall floppiness, difficulty feeding, or a weak cry.

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.
