Find out what determines baby’s eye color (it's not just the parents!), whether all babies are born with blue eyes, plus when do babies eyes change color?

When Do Babies Eyes Change Color? Will They Stay Blue?

So your baby was born with a full head of hair and piercing blue eyes? It may surprise you to learn that, in a few months time, baby could have no hair and green eyes. Baby changes rapidly in that first year, so if your child was born with those baby blues, you’ll probably wonder will they change color—or will they stay blue? When do babies eyes change color?

When Do Babies Eyes Change Color?

If your child is born with those baby blues, you’ll probably wonder when do babies eyes change color? Will they change color—or will they stay blue? 

It can take as long as 9 to 12 months for your baby’s permanent eye color to be determined and the change is so gradual, you might not even notice it happening. But by baby’s first birthday, you can be pretty sure whatever big eyes are staring down that smash cake are the ones they’ll have for life.

“Though some babies’ eye color changes rapidly with the onset of melanin, most infants undergo significant changes between six and nine months of age. This phenomenal occurrence happens once the iris has stored enough pigment to influence subtle changes like blue to grey, green to hazel, hazel to brown and so on.”(source)

Keep in mind that eye color generally gets darker, not lighter. Your brown-eyed girl isn’t likely to become blue-eyed later in life. But your blue-eyed boy may very well end up with green or even brown eyes.

Can You Tell if Baby’s Eyes Are Going to Change Color?

As noted above, if baby is born with brown eyes, he/she will almost certainly have those brown eyes for life. If baby has blue eyes, this simple (but not foolproof!) trick can help determine whether or not they’ll stay that way. (source)

  1. Look at baby’s eye from the side to eliminate any light reflecting off the iris.
  2. If there are flecks of gold in the blue of the eye, your baby’s eyes will likely change to either green or brown as they grow.
  3. If there are minimal or no flecks of gold, it’s less likely your baby’s eye color will change much.

Another indicator? If baby’s eyes are clear, bright blue, they are most likely staying blue. If they are a darker, cloudier blue, they are most likely going to change to hazel, brown, or a darker color.

What Color Eyes Will My Baby Have?

There’s no way to know for sure what color eyes your little one will have.

Recent research suggests there’s a lot more than parents’ eye color that affects baby’s eye color, but you can generally expect:

  • Two blue-eyed parents to have a blue-eyed child.
  • Two brown-eyed parents to have a child with brown eyes.

  1. Mama Natural,
    Thanks for all the wonderful resources you bring. I read your story on Faith from this 3 Things for Friday. Beautiful.
    I was checking this out, and on the image the blue + blue eyes are supposed to show 99% blue and 1% green right? I think it got switched around but the text in the article is correct.

  2. I have blue eyes and my husband has dark brown eyes and we have three children together. Our firstborn had dark gray eyes at birth and now has very brown eyes and brown hair. Our second child had red hair at birth and light gray eyes. Now eyes are light blue and hair is strawberry blonde. And our third had grayish blue eyes at birth and blonde hair but when he turned one his eye color seemed to still be changing. One day i’ll say yepp they’re blue but the next they’ll look tan and gray. I’ve also seen green. Not sure what’s up with those eyes!

  3. The chart isn’t correct for 2 blue eyed parents. The green and blue should be reversed.

    My mom has brown eyes, my dad has green and so do I. My brother and sister have brown. All of my kids have blue eyes, like their dad. Hopefully at least one grandchild will have green. lol

  4. Interesting post! You mention a pair of blue eyed parents being most likely to have blue eyed babies. But the graphic indicates almost certainly green eyed babies from a pair of blue eyed parents? I think there is a “typo” here?

  5. My husband and I both have hazel eyes. Definitely more green than brown and our son has brown eyes

  6. The eye color chart is incorrect. Blue plus blue should be 99% blue not 99% green.

  7. You might want to double check the image at the top. Two blue eyed parents aren’t 99% likely to produce a green eyed child…
