How to stop my child from being a cry baby?

While the crying is distributed through the day, sometimes the child doesn't stop crying because of something causing discomfort. I would suggest you to first check whether he is bothered by anything causing discomfort or does he react like this every time. When the child is ill he may cry louder and for longer but that should not be understood as a sign of cry baby.
