Aren’t newborn babies fascinating? While they’re undoubtedly cute and tiny, the little humans are also a little weird and fascinating. Besides eating, sleeping, and pooping, there’s so many things we don’t know about them!

Here are a few interesting facts about your newborn that may help you feel like you understand them a little better:

1. Their hearts beat faster than adults

A newborn baby’s heart beats 130 to 160 times per minute – about twice the heart rate of a normal adult! That is because babies burn food in every cell of their bodies to fuel their amazing growth. Furthermore, a baby breathes between 30 to 50 times a minute whereas adults only breathe between 15 to 20 times a minute.

2. Newborns can’t taste salt!

While newborns are born with a well-developed sense of taste, studies show that babies can’t taste salt until they’re about 4 months old. Some studies also suggest that babies taste other flavors better than adults can (especially sweet, bitter, and sour) because they have more taste buds than adults do.

3. They are born with a reflex called the bradycardic response

The bradycardic response (aka the diving reflex) gives babies the ability to hold their breath and open their eyes when submerged in water. However, it doesn’t mean that babies are born with the ability to swim though. Experts note that they aren’t old enough to hold their breath intentionally or strong enough keep their head above water.

4. They don’t shed tears

They may cry a lot, but newborns don’t shed tears because their tear ducts and glands produce just enough tears to lubricate and protect their eyes. Look for those teardrops to start flowing between 3 and 12 weeks old.

5. Babies have more bones than adults

Although we’re taller and bigger, we actually have lesser bones than a newborn. According to scientists, a baby has about 300 bones while adults have 206. The reason for the loss of bones is due to fusion of the spine and skull as baby grows. For instance, the human skull starts off as several separate bones that fuse together into one large bone by about the age of 2.
