Respuesta :
By the end of the second month, a baby usually flashes his or her first social smile. In part because of this, it gives me great pleasure as a pediatrician to see parents and babies at the 2-month checkup.
What is the average age at which infants start grinning at people easily?
Your infant will have a "social" smile around the age of two months. That smile was intended to make the other person feel welcome. Babies form attachments to their caregivers between this time and about 4 months of age. For familiar caregivers as opposed to unfamiliar ones, they will more easily stop crying.
Can a five-week-old baby grin socially?
By the age of five weeks, you can safely assume that when your baby's mouth corners curl up, it's a genuine social smile — unless, of course, you happen to smell that distinctive smell that signals it's time for another diaper change.
