I often see young children being told "it is ok" or "calm down" when crying because they are hurt or sad. I know the parents probably feel like others are staring at them or judging them. Honestly though, I am thankful when a parent scoops up a child who is having a hard time and validates the child's feelings. We all have feelings. We all have the right to express those feelings in a safe way. Young children often do this by crying. Crying relieves pressure and stress.
Please validate your child's feelings as normal and necessary. No one thinks you are bad parent because your child has feelings. If a child is stifled and bottles feelings up now, he or she will not be able to work through larger emotions when grown. Eventually all those bottled feelings WILL come out very possibly in a less than safe manner. This is most definitely part of why we have violence in the world.
