my baby is 1 month 25 days old.. she is only responding to loud sounds like callingbell in sleep only...awake time she is not responding...she doesn't observing the toys & me... not giving social smile also..

A. when the child is smiling without any interaction that is not social smile. a social smile is reciprocal, meaning your baby smiles in response to someone else's smile. the vision as well as the brain of the child is matureing in a proper way when the child is smiling on seeing a person. it says he's able to see short distances, make sense of an object (in this case a smiling face), and produce his own smile in return. s a social smile also boosts bonding, since it's one of the first forms of communication between parent asnd child. if despites your encouraging grins you don't notice a social smile by 4 months, bring it up with your pediatrician; rarely this can signal eye problems or a developmental delay.
