It is OK to tell your child to shut up if they are really misbehaving.
However if they are being good and just being loud then telling the child to shut up is not a good thing unless they are actually disturbing others or yourself.
If the child is screaming and throwing a tantrum then telling them to shut up is okay.
However if they are just being loud and making a lot of noise and you want them to be quieter you should calmly tell the child to quiet down and not be as loud.
Telling a child to shut up can make the child feel unimportant, disregarded and damage their self worth.
Commando parenting is a parenting style that involves parents setting strict rules, discipline and lack of emotional connection with the child.
Commando parents are strict and are in charge and expect their children to follow all rules without any question.
Being a commando parent can result in lacking of the warmth and nurturing that is important for healthy child development.
A commando parent often uses guilt, shame, fear or punishment to control their children's behavior.
In commando parenting it's also all or nothing as commando parents often take way a child's favorite clothes or access to media devices, TV, computer etc as punishment.
And to earn these things back the child has to earn back the items as their behavior improves.
The commando parenting style is also similar to authoritarian parenting that is also rule bound and very demanding.
Although commando parenting is also considered to be more intrusive and more extreme than authoritarian parenting.
Going the commando parenting route when parenting can have negative consequences for children, which include over dependence on parents, difficulty maintaining and forming relationships, low self esteem, resentment and lack of trust.
The commando parenting style is also controversial.
