It’s hard not to feel overjoyed when your baby gazes adoringly into your eyes and flashes a brief, but unmistakable smile. This is the magic power of the sweet, contagious smile they have. Very young infants start laughing on the first month of life, although others may wait up to the fourth month of age. But, here in this video, a newborn baby gives few hints smile which is so cute to watch.

Babies probably start smiling long before they were born. Babies can smile very early in life, even in utero, says Mark Gettleman, M.D., a pediatrician and owner of Dr. Goofy Gettwell Pediatrics in Scottsdale, Arizona. These first smiles aren’t intentional or in response to anything. They’re reflex smiles, similar to the jerky arm and leg movements your baby’s body experiences as it goes through the equipment-testing process, Dr. Gettleman says.
