Smiling and newborns

Seeing a baby smile is one of the greatest joys in life, but it may seem like forever until Baby starts smiling.

When do newborns start smiling?

You might be wondering when he will begin smiling back at you when you talk to him, or you might have noticed a reflex smile in his sleep. Most newborns begin to smile between 6 and 12 weeks, but everyone is different, so you might notice Baby smiling before or after that. A smile is a sign that Baby’s vision is developing and his cognitive awareness is improving. It’s also a sign that he wants to start communicating with you.

Why babies smile

Babies use smiling to communicate with you, and begin making facial expressions both in the womb and after birth. Smiling at Baby allows him to start to learn and mimic your facial expressions, and you can start to encourage him with your expressions as early as his first few weeks. You will be able to tell the difference between a reflex and learned smile by Baby’s reaction to outside stimuli – as Baby gets older and more aware of the world around him, if a smile seems like a response to something, it probably is. Often during a “real” smile, his entire face will light up and you will see the smile in his eyes.

What’s next?

Once Baby begins smiling, he will repeat this behavior as long as you encourage it. To encourage smiling, try talking to him often, making funny faces, starting a tickle war, or, as he gets a little older, maybe between 5 and 7 months, playing peek-a-boo. Pretty soon, you might notice those first adorable newborn giggles, so get excited!
