1. Cartilage formation.
When children are born, they have cartilage that will later turn into knee caps. This soft, easy-binding tissue is very important for children to learn to move, especially around the sixth month.
2. Their vision has great contrasts.
Newborns can focus between 200 and 400 meters from their face. They see most clearly images that have high contrast, for example black and white. They do not yet have the ability to distinguish all colors.
3. Weight at birth.
Usually male babies weigh more than little girls at birth. The average weight in boys is between 2 kg and 500 g and 4 kg and 300 g. In girls it is between 2 kg and 300 g and 4 kg and 200 g.
4. The number of bones.
When they are born, the skeleton of babies is not fully formed. Then they have 300 bones. As the child grows, some bones will form complex structures. When he grows up, there will be 206 bones in his body.
5. Sense of taste.
A newborn baby has about 10,000 taste receptors on the tongue. They are much more than those of adults. As the years go by they will start to decrease.
The newborn should sleep a total of between 15 and 17 hours per day. They sleep for short periods of time. Their naps last between 2 and 4 hours in the first weeks.
7. The pulse.
Another interesting fact that parents learn is that their pulse is much faster. The baby’s heart beats 130 to 160 times per minute. That’s almost twice the adult pulse rate.
Children are born with well-developed hearing. They understand instantly where the sound or voice comes from. This happens in the first ten minutes of their lives.
9. Breathing and swallowing.
It is characteristic of babies that they can do two important actions at the same time, which assists their feeding: breathing and swallowing. This ability disappears at about the seventh month.
10. Hair color and density.
Hair colour and density can change after birth. Hair can fall out, and then it will grow back. Colour and density may also vary.
Reflexes are the body’s automatic responses. Newborn babies have a lot of them. They are born with about 70 primitive reflexes that disappear with time.
12. Exploring the world.
Young children explore their surroundings by touch. The most sensitive part of their body is the mouth. That’s the reason they keep putting stuff in it too.
13. Eye color.
Many babies have blue eyes at birth, which change at a later stage. This is due to melanin. The pigment that forms the eye color has not yet developed. The true eye color is revealed around the sixth month.
