My baby like to wake up during midnight !!

There was a young couple told me one day, why my baby like to wake up at 3 am and play around actively ? At first, i thought it was normal, as their baby was just born. However, when time pass, they still face the same situation. Then only i remembered, i faced this scenario before with my daughter, coincidentally, theirs also a daughter. Is it because of gender? Or because of genetic? Or they sleep too much during daytime?

The answer is......the baby still do not recognize between day time and night time. How do i know? Actually i don't. Someone told me, perhaps based on their experiences, the baby need to be trained to recognize between dark and bright. Thus, i told the couple, just make sure you do not switch on the light when the baby awake. Use some dim light to make milk only, and quickly switch off the light. And at all time, make sure no light during night time. And during day time, try to play with her as much as possible, and of course, you cant block the sun light from the window. From these, the baby will learn to differentiate between day time and night time.

Guess what? It worked. It really worked.
