Your little one loves to hear your voice as its reassuring, loving and comforting. Research shows that when your baby hears your voice, there is increased activity in many areas of the brain especially the area of the brain associated with rewards. For instance, “Oh! that’s Mom’s voice. She will hold and comfort me.”
What you need to know
When your baby cries, your warm arms and voice will calm him. As he hears your voice, it can stop his crying, bring a smile or generate excitement. If he is hungry, feeling cold, is uneasy, all such needs are communicated by him through crying. The moment he hears your voice, the discomfort either vanishes or reduces to a greater extent.
