Newborns tend to prefer the sound of the human voice. So your singing, cooing, and talking to them soothes them. They’ve heard mommy’s and daddy’s voices in the last 3 months of pregnancy because their auditory system was already functioning, There are some reports of newborns recognizing their parents’ voices at birth. Newborn babies also smile reflexively. This smile typically occurs when the cheek or lips are touched or in light sleep. You’ll know it’s a reflex because the area around the eyes doesn’t crinkle— a significant difference between social and reflexive smiles. Nonetheless, this reflexive smiling helps to set the stage for face to face connection, attention, and continued learning. These early abilities probably help newborns to “tune in” to their parents and set the stage for parent-child attachment.
