Usually the most noticeable change happens at 6-9 months. By 12 months, most have their permanent eye color, but some can change up to 6 yrs old (very rare cases).
My DS's eyes went brown by about 2 weeks & stayed that way (he is amost 4), DD's are still blue at 3 weeks so we will see if she ends up blue, green like mine or brown like hubby
