Why don't newborn babies cry real tears?

Have you ever wondered why your newborn baby might be screaming at the top of their lungs, but no tears are coming out of their crying eyes?

The reason is incredibly simple - their tear ducts haven't developed yet.

Tear ducts don’t actually develop until babies are two months old, although some can develop from two weeks onwards - both are entirely normal.

'While newborns are born with working tear ducts and glands, they only produce enough tears to lubricate and protect the eye, which means there's no excess to roll down your baby's cheeks when they cry', says Dr. Jennifer Shu, co-author of Heading Home With Your Newborn.
