Good morning, moms. When did your kids decide on their eye color? The elder was born with brown eyes, by two months the color became richer and hasn't changed since then. The younger one was born with dark gray eyes, over time they slightly lightened, but not much and seem to be both gray and slightly brown. It's interesting at what age will the child's eye color become clear? My husband has brown eyes, I have light gray ones.
