Is it normal for newborns to cross their eyes?

Why This Happens

There are several physiological reasons why a newborn’s eyes might not always look straight or aligned. In the early weeks of life, the visual system is still “wiring” itself.

• Developing Eye Muscles: The muscles that control eye movement are not yet fully strengthened or coordinated, which can cause the eyes to drift inward or outward.
• Lack of Binocular Vision: Newborns cannot yet merge the images from both eyes into one single 3D image, meaning their eyes may move independently.
• Focusing Difficulties: Infants are still learning how to track objects and focus on faces, which often leads to temporary misalignment as they attempt to lock onto a target.

What It Might Mean in Your Situation

Understanding whether eye-crossing is a normal developmental phase or something that requires attention depends on the pattern and timing. For most parents, this is a temporary phase that resolves on its own as the baby matures.

Consider the following factors to get a better sense of the situation:

• Consistency: Does the crossing happen only occasionally, or is one eye constantly turned in or out? Occasional crossing is typically normal; a permanent turn may be different.
• Timing: Is this happening in the first few weeks of life? Most pediatricians consider occasional crossing normal up until about 3 to 6 months of age.
• Responsiveness: Does the baby seem to be attempting to track your movement or a toy, even if the eyes aren’t perfectly aligned?
• Family History: Some families have a genetic predisposition to strabismus (misaligned eyes), which may make these occurrences more common.

What To Do About It

1. Observe and Track: Keep a mental or written note of when the crossing occurs. Note if it happens more when the baby is tired, trying to focus on something very close, or just waking up.
2. Encourage Visual Stimulation: Gently hold high-contrast toys (like black and white patterns) or your face about 8 to 12 inches from their face to encourage them to practice focusing and tracking.
3. Mention it at the Next Check-up: Bring your observations to your baby’s next scheduled pediatrician visit. You can say, “I’ve noticed the baby’s eyes cross sometimes; is that typical for their current age?”

Real-Life Example

Sarah noticed that her six-week-old son’s eyes crossed whenever she brought her face very close to his during feeding. She felt concerned that he might have a vision problem. However, she also noticed that when she moved a colorful toy slowly across his field of vision, his eyes eventually aligned and followed the object. During her next pediatrician visit, Sarah mentioned the crossing. The doctor explained that this is a common part of infant development and that the baby’s eyes would likely straighten out as his muscles strengthened over the next few months.

When To Seek Outside Help

While occasional crossing is common, you should contact a healthcare provider if you notice a persistent, constant misalignment that does not go away, or if the eyes seem to be shaking (nystagmus). If you have concerns about your child’s neurological development or if the eye crossing is accompanied by a lack of response to visual stimuli, a referral to a pediatric ophthalmologist may be useful for a professional diagnosis and a specialized care plan.
