Saman is 20 months old

About a week back on Falgun 16, 2073 (February 27, 2017), saman was 20 months old.
He can climb up and down the stairs.
He loves picture books a lot and can relate animal with their sounds well. His special book this time is "माला" and "डोजर". He is very good at saying a big "NO". He asks questions a lot, whats that?, why is that?, where is that? and so on, it seems he is trying to learn everything around.
He is slowly becoming physically independent, he can kick a ball or balloon well, he loves playing a ball passing. Till now it seems that he knows very little about safety so he wants to do everything in his own way. Similarly he wants to help whatever we do in front of him like brooming, cutting vegetables, typing on laptop, etc.
He can make puzzle blocks tower. He has developed a craze for screen, specially watching cars in ipad and phone.
He is very particular about personal belongings, like he wants my sandals to be used only by me.
He sometimes let us know about bowel movements, and sometimes not.
This time he shows tantrum a lot, it seems like he has learned that is the way to get somethings he wants. Whatever he wants, he waits for the correct time and whenever he gets the chance he just grabs the thing and run away, specially from his brothers and other kids.
Finally he wants to eat everything by himself and he is a messy eater.
