Smiling Babies

• Babies smile during sleep from the day they’re born.
• Infant smiles have nothing to do with gas.
• Your baby will respond to, and smile at, auditory stimulus (such as your voice) before visual.
• At two to three months, your baby starts to look right at you when she smiles.
• By six months, your baby will have different smiles – open mouth smiles usually indicate more joy than closed.

Babies usually don’t start social smiling until about eight months, but their smiles can still say a lot before then. “In fact, babies smile when they’re asleep from birth,” says Dr. Daniel Messinger.
