Babies have more bones than adults. They are born with about 300 bones, while adults have 206 due to the fusion of some bones as they grow.

A baby’s taste buds are more sensitive than those of adults. They can taste a wider range of flavors, which may explain why they can be picky eaters.

Newborn babies can recognize their mother’s voice from birth. They are also able to recognize familiar sounds they heard while in the womb.

Babies have a strong sense of smell. They can differentiate between their mother’s breast milk and that of another woman.

On average, a baby will triple its birth weight within the first year of life.

Newborn babies are nearsighted and can see objects clearly only at a close distance. They can see best at a distance of 8-12 inches, which is roughly the distance between their face and their mother’s while breastfeeding.

Babies don’t have kneecaps at birth. Instead, they have soft cartilage that eventually hardens into kneecaps as they grow.

The brain of a baby doubles in size during the first year of life.

A baby’s heart beats faster than an adult’s. The average heart rate for a newborn is around 120-160 beats per minute.

Babies have a higher body surface area-to-weight ratio than adults, which makes them more susceptible to changes in temperature.
