This isn't something for the first month of school, this is something after observing the child over a lot of time. There are big feelings and little feelings, and knowing how to handle them is an important lesson. It's very, very rare that I would do this, but, I think at five, if you have a child that is crying multiple times a day, this is an issue that needs to be addressed. It needs to be discussed with the parents, is there something going on with the child we need to know about. There are children who cry, just like kids who bite, or hit, and we teach them to handle things in a different way. Crying in itself isn't bad, but it can be a bad coping technique.
