In the first months of life, the newborn knows the world through the senses: sight, hearing, touch and smell. No special stimuli are needed: face, voice and repeated routines build trust. To support your sight, show high-contrast objects (black and white or clear colors) about 20—30 cm away: this is the distance at which he sees best.Bring your face closer to his as you speak to him: newborns are attracted to human facial features and they soon learn to recognize them.Your voice is the most reassuring sound: speak, sing, respond to his vocalizations. The rhythm and the alternation between 'voice and response' help him understand that communication is a mutual exchange. Avoid loud or sudden noises: constant, familiar sounds (voice, water, heartbeat) help him to calm down. Repetitive activities (a song, a lullaby) create predictability and security.
