No bones about it

A newborns kneecap is made entirely of cartilage. Through a process called ossification, the cartilage slowly converts to bone. During early years, a kneecap wont even show up on an X-ray. It usually takes anywhere between 3 to 5 years after birth for kneecaps to develop into real bones.

Tiptoeing around

Children who are just learning how to walk often start by walking on the toes or ball of the foot, which is referred to as toe walking. It is typically outgrown, but some kids continue the practice beyond their toddler years simply out of habit. According to the Mayo Clinic, as long as your child’s growth and development is normal, then toe walking shouldn’t be a major concern on its own.

Seeing double

According to a 2012 report from the National Center for Health Statistics, the occurrence of twin births has risen from 1 in every 53 babies in 1980 to 1 in every 30 in 2009.

Brain power

A baby’s brain at birth contains 100 billion neurons, which are the nerve cells within the brain. Comparably, there are about as many nerve cells in a baby’s brain as there are stars in the Milky Way. A baby’s brain starts developing around three weeks after conception.
