At baby's birth, he or she is only able to see clearly about 8 to 12 inches in front of her, in other words, the perfect distance for studying faces and familiarising themselves with those who are close like mommy and daddy. Some studies suggest that babies may be able to recognise their parents' faces within days of birth, but others opine that it could take up to two months. Baby's vision will continue to improve gradually throughout his or her first year. It is observed that by the eighth month, baby will be able to recognise his or her parents from across the room. http://www.babycenter.com/408_when-will-my-baby-recognize-me_1368483.bc
babies will be better able to recognize faces from around the time they are 2 months old, but that does not mean they will be able to recognize all faces. at this age, your baby will be able to recognize the main caregivers.
around the 2nd month your baby will be able to recognize few of the faces who are the primary caregivers.
