Most babies naturally outgrow crossed eyes by 3 to 4 months as their eye muscles and coordination develop.
Understanding Why Babies Appear Cross Eyed
It’s quite common for newborns to look a little cross eyed. This happens because their eye muscles are still developing and coordinating. In the first few weeks of life, babies often have trouble focusing both eyes on the same object, leading to a temporary inward or outward crossing appearance. This isn’t usually a cause for concern.
Newborns’ vision is blurry at birth, and their brains are just learning how to control their eye movements. The muscles that control eye alignment are weak and immature. As a result, you might notice your baby’s eyes wandering or crossing occasionally while they’re sleeping or even when they’re awake.
The good news is that this phase is generally temporary. Most babies develop proper eye coordination naturally as their visual system matures during the first few months of life.
Eye Muscle Development in Infants
The muscles responsible for moving the eyes—called extraocular muscles—need time to strengthen and synchronize. In early infancy, these muscles don’t always work together perfectly, which causes the crossed-eye appearance.
By around 6 to 8 weeks of age, babies start focusing more steadily on objects and faces. This increased focus helps train the eye muscles to align properly. The brain also plays a crucial role by learning how to process signals from both eyes simultaneously, which is essential for depth perception and clear vision.
For most infants, muscle coordination improves steadily between 2 and 4 months of age. This is why crossed eyes usually resolve during this period without any intervention.
The Role of Brain Development in Eye Coordination
The brain’s visual centers must develop alongside the eyes for proper alignment. Early in life, the brain is still figuring out how to merge images from each eye into a single picture—a process called binocular vision.
If one eye sends a blurry or misaligned image consistently, the brain may start ignoring that input, leading to amblyopia (lazy eye). Therefore, it’s vital that both eyes work together well early on to prevent long-term vision problems.
This neurological development explains why some babies who remain cross eyed beyond 4 months might need medical evaluation. Persistent misalignment can interfere with normal visual development if left untreated.
When Do Babies Stop Being Cross Eyed? Typical Timelines
Most babies stop being cross eyed by about 3 to 4 months old as their eye muscles strengthen and coordination improves. Here’s a breakdown of typical milestones:
| Age Range | Eye Appearance | Expected Development |
|---|---|---|
| Birth – 6 weeks | Frequent crossing or wandering eyes | Normal due to immature muscle control and blurry vision |
| 6 – 12 weeks | Less frequent crossing; improved focus on faces/objects | Muscle coordination strengthens; brain adapts for binocular vision |
| 3 – 4 months | Eyes usually aligned consistently | Most infants stop being cross eyed naturally by this age |
| Beyond 4 months | Persistent crossing or drifting of one or both eyes | May indicate strabismus needing medical assessment |
If your baby’s eyes continue crossing after 4 months or if you notice one eye drifting outward or inward consistently, it’s time to consult an eye specialist.
The Difference Between Normal Crossing and Strabismus
Strabismus is the medical term for persistent misalignment of the eyes beyond infancy. Unlike normal early crossed eyes that improve with time, strabismus requires professional evaluation and often treatment.
Strabismus can take several forms:
- Esotropia: One or both eyes turn inward.
- Exotropia: One or both eyes turn outward.
- Hypertropia: One eye drifts upward.
- Hypotropia: One eye drifts downward.
This condition affects roughly 4% of children worldwide and can lead to amblyopia if untreated. Early detection is key because treatment success rates are highest when started before age two.
Signs That Strabismus May Be Present in Your Baby
- Eyes that frequently cross or drift apart when looking at objects.
- Squinting or closing one eye in bright light.
- Tilting or turning the head to see better.
- Poor depth perception as baby grows older.
- Lack of coordinated eye movements when tracking moving objects.
If any of these signs persist past four months, seeking an ophthalmologist’s advice is crucial.
Treatment Options for Persistent Crossed Eyes in Babies
If your baby continues being cross eyed after the typical timeframe, treatments vary depending on severity and cause:
- Patching Therapy: Covering the stronger eye temporarily forces the weaker one to work harder.
- Glasses: Corrective lenses can help if refractive errors contribute to misalignment.
- Surgery: In some cases, surgery adjusts the position or length of extraocular muscles to realign the eyes.
- Eye Exercises: Special exercises guided by an optometrist may improve muscle strength and coordination.
- BOTOX Injections: Occasionally used as a less invasive option than surgery.
Early intervention dramatically improves outcomes. Treatments aim not just at cosmetic correction but at ensuring healthy visual development and preventing lazy eye.
The Importance of Regular Eye Checkups in Infancy
Pediatricians typically screen infants’ vision during well-baby visits but may refer you sooner if concerns arise. A comprehensive pediatric ophthalmologic exam includes assessing:
- Stereopsis (depth perception)
- Pupil response and reaction to light
- Eyelid position
- Eyelash alignment
- The ability of both eyes to track moving objects together
- The presence of any refractive errors like farsightedness or astigmatism
Early detection allows timely treatment before permanent vision loss occurs.
The Role of Genetics and Other Factors in Eye Alignment Issues
Some babies are more predisposed than others due to genetics or other factors such as:
- A family history of strabismus or amblyopia increases risk.
- Certain neurological conditions can affect muscle control.
- Craniofacial abnormalities may impact how the eyes align.
- Nutritional deficiencies during pregnancy could play a minor role.
- Certain premature births show higher incidence rates due to underdeveloped systems.
Understanding these factors helps pediatricians monitor at-risk infants closely for early signs.
A Closer Look at Premature Babies and Eye Alignment Challenges
Premature infants often have delayed development across multiple systems—including ocular muscle control—due to shorter gestation periods. They may take longer than full-term babies to stop being cross eyed.
Additionally, premature birth increases risk for retinopathy of prematurity (ROP), which can affect retinal blood vessels leading to vision problems requiring specialized care.
Parents should ensure frequent follow-ups with neonatologists and ophthalmologists familiar with prematurity-related risks.

Frequently Asked Questions
When Do Babies Stop Being Cross Eyed Naturally?
Most babies naturally outgrow crossed eyes by 3 to 4 months as their eye muscles strengthen and coordination improves. This phase is common and usually resolves on its own without any medical intervention.
Why Are Babies Cross Eyed in the First Few Months?
Babies appear cross eyed early on because their eye muscles are weak and uncoordinated. Their brains are still learning to control eye movements, causing temporary inward or outward crossing, especially in the first weeks of life.
How Does Brain Development Affect When Babies Stop Being Cross Eyed?
The brain’s visual centers develop alongside the eyes to enable proper alignment and binocular vision. If the brain struggles to merge images from both eyes, it can delay when babies stop being cross eyed and may require evaluation.
When Should Parents Be Concerned About Babies Being Cross Eyed?
If crossed eyes persist beyond 4 months, it’s important to seek medical advice. Persistent misalignment can interfere with normal vision development and may need treatment to prevent long-term issues like amblyopia.
What Role Do Eye Muscles Play in When Babies Stop Being Cross Eyed?
The extraocular muscles controlling eye movement need time to strengthen and synchronize. As these muscles develop between 2 and 4 months, babies gain better eye alignment, which is why crossed eyes typically resolve during this period.
Caring Tips for Parents Observing Crossed Eyes in Their Baby
Seeing your little one with crossed eyes can be worrisome but keep these tips in mind:
- DON’T panic: Most cases resolve naturally by four months old without intervention.
- DON’T ignore persistent symptoms:If crossing continues past four months or worsens, get an expert opinion promptly.
- DON’T self-diagnose:A professional exam ensures accurate diagnosis versus normal developmental variations.
- DON’T delay follow-up appointments:Your pediatrician will guide timely referrals if needed.
- DON’T forget developmental milestones:If your baby struggles with tracking objects visually beyond expected ages, mention this during checkups.
- The saccadic system (rapid eye movements) begins maturing allowing quick shifts between focal points.
- The smooth pursuit system (tracking moving objects) improves gradually enabling better following ability.
- The vergence system (both eyes moving inward/outward together) strengthens helping maintain single binocular vision instead of double images.
These coordinated functions depend heavily on practice from repeated visual experiences interacting with caregivers’ faces and surroundings.
