Why do babies sleep so much?

The “baby sleep” is one of the most important and interesting aspects of their development during their first year of life. It is normal for a baby to sleep for up to 16 hours, although 50 percent of that time his brain remains active.

While the baby sleeps, his organs performs essential functions for his optimal development, for example his intellectual abilities are reinforced. Also during sleep, the baby secretes more of a hormone known as "growth hormone." This means that sleeping well helps the baby to grow.

Something very curious is that while the “adults sleep” is made up of 5 parts, “babies sleep” only has 2. Babies only have active sleep (light sleeping) and quiet sleep (heavy sleeping) in brief sleep cycles of around 50 to 60minutes as compared to the adult sleep cycle which is up to eight hours.
