The full narration of the video.
You lean in close to a newborn, and your heart skips: one eye is looking right at you, the other is drifting toward the nose. Lots of parents think the same thing first: uh-oh, is my baby cross-eyed? Usually, no. At birth, a baby's two eyes are basically strangers. They haven't learned to work as a team yet.
To look at something, both eyes have to aim at the same spot at the same moment. Like two people carrying a table, they have to call out the steps and move together. The one calling the steps is the brain. But a newborn's brain hasn't practiced those calls yet, and the tiny muscles that turn each eye don't quite listen. So now and then the two eyes go their own way: squeezing in, drifting out, then lining up again.
A British researcher who studies baby vision looked at over a thousand babies. In the first two months, this was common. It faded after two months, and was mostly gone by about four. So what if, at four months, your baby still looks a bit cross-eyed? Look at the nose. A baby's nose bridge is low and wide, and a little fold of skin often covers the inner corner of each eye.
That hides the white of the eye on the nose side. So the dark part looks squeezed inward. The eyes are actually straight — the nose is fooling you. This fake cross-eye is more common in Asian babies. Most outgrow it by two or three, once the nose bridge grows. For a rough check: have your baby face the phone and take a flash photo. Look at the tiny dot of light in each eye. If both dots sit in the same spot, the eyes are probably straight.
It's only a hint — an eye doctor gets the final say. One last oddity: why do baby eyes look so big and dark? At birth, the eyeball is about sixteen and a half millimeters long. An adult's is about twenty-four, so it's already two-thirds grown. But how big is that little face?
So on that small face, the eyes look huge. As for color, most Chinese babies are born with dark brown eyes, which may only get a little darker. When should you see a doctor? If after four months one eye is still often turned, or it's always the same eye drifting in or out, go sooner rather than later. So those odd baby eyes are two eyes learning to team up, plus a nose bridge that hasn't grown up yet.
When your baby was little, did anyone ever say they were cross-eyed?
One eye on you,
one drifting to the nose
Lean in close to a newborn and your heart may skip: one eye is looking right at you, the other is drifting toward the nose. Uh-oh — is my baby cross-eyed?
Usually not. At birth,
the two eyes are strangers
that haven't learned teamwork.
Two eyes carry a table,
the brain calls the steps
To look at something, both eyes must aim at the same spot at the same moment — like two people carrying a table, calling out the steps. The brain does the calling. But a newborn's brain hasn't practiced the calls yet, and the tiny muscles that turn each eye don't quite listen.
So now and then the eyes go their own way: squeezing in, drifting out, then lining up again.
About four months
of practice
A British baby-vision researcher looked at more than a thousand babies: in the first two months this was common, it faded after two months, and was mostly gone by about four.
Newborns also see very blurry — only about 20–30 cm (8–12 inches) clearly, roughly the distance to your face during a feed.
Still cross-eyed at four months?
Look at the nose
A baby's nose bridge is low and wide, and a little fold of skin often covers the inner corner of each eye. That hides the white on the nose side, so the dark part looks squeezed inward.
The eyes are straight.
The nose is fooling you.
This "fake cross-eye" is more common in Asian babies. Most outgrow it by two or three, once the nose bridge grows.
Take a flash photo,
check the two dots
Have your baby face the phone, take a photo with the flash on, and look at the tiny dot of light in each eye. It's only a hint — an eye doctor gets the final say.
Big and dark:
eyes grow first, face later
At birth the eyeball is about 16.5 mm long; an adult's is about 24 mm. It's already two-thirds grown — but that little face is tiny, so the eyes look huge.
As for color, most Chinese babies are born with dark brown eyes that may only get a little darker. The famous "babies are born with blue eyes" is mostly about fair-skinned babies of European descent.

Quick check
Why do a newborn's two eyes often fail to line up?
Like two people carrying a table, the brain is still learning to call the steps; by about four months the eyes mostly line up.
