My newborn smiles in their sleep but doesn't smile at me by looking at me. When does real, social smiling start?

A newborn's smile during sleep is completely reflex — called 'newborn reflex smile' and comes from involuntary muscle movements as baby's nervous system develops. Real, social smiling (that is, smiling while looking at you, showing they recognize you — that magical moment) usually starts around 6-8 weeks. Some babies do it at 5 weeks, some not until 10 weeks; both are normal. Starting around week 6, your baby will hold eye contact longer and when they focus on your face, you may see that first social smile. During this time, talking to them in a soft voice is the most powerful thing that triggers that smile.
