If you've ever been around a newborn, you're likely to gush over chubby fingers and melt into glistening blue eyes that gaze around a post-utero world. Perhaps a year later you see little Johnny again as he smashes his face into the sweet crumbles of his first birthday cake.
Between smears of buttercream frosting, you notice his eyes are brown. This can't be the same baby — his eyes were blue just a few months ago.
Don't worry, there's no cause for alarm. That cake covered brown-eyed baby is the same blue-eyed newborn. Changing eye color is a normal part of baby development. Anywhere from 9 months to 3 years old, a baby's eye color "sets" on a single hue (or in rare cases two colors called heterochromia) as more melanin is released into their eyes. That's why when you saw little Johnny's eyes at his first birthday party, they were no longer blue, they were brown.
