I worry more about those children who are quiet and docile, and who rarely cry or rage. It usually has nothing to do with the event that triggered the screaming and tears. This is what children do frequently, and it looks as if they are overreacting or trying to manipulate adults. This is usually not the case. They are simply releasing stress.
Children feel safe to cry and rage when they are confident of being loved and accepted.
It implies that the children are feeling safe. Children need at least one person with whom they can release their most intense emotions. It is best if this person can accept the child no matter how she is feeling, and not try to stop the crying or tantrum. The more a child can cry and rage at home, the less likely she will be to have emotional outbursts in public. I recommend staying with your daughter during her tantrums.
