Although you can’t predict the exact age your baby’s eye color will be permanent, most babies have the eye color that will last their lifetime by the time they’re about 9 months old. However, some can take up to 3 years to settle into a permanent eye color.

I thought eye colour was determined by six months of age. I’m not sure when my daughter’s eyes stopped changing colour.

Babies’ eyes tend to change color sometime between 6 and 12 months, but it can take as long as three years until you see the true color of what their eyes are going to be

Just as an answer..
Her eyes are now a deep brown!
