Day by day become very naughty

Since last weekend sickness, Yishion had become very naughty. I take care him until I lost the temper. He do not want to sit or lie down on his own. Even carry him sitting on his lap he also refuse to. He keep on yelling and crying.
My collegue says that most of the child, when after sick they would like this. Oh gosh... Is it all the CHILD in the world like this? Why there is no good people anymore in the world?
It is not easy to become a MOM.....
