A child of 9 sulking excessively whenever they do not get their own way? For example they will be told they cannot do something and they will sit there with their head down for ages and a moody expression or will walk off and sulk. Or they will be asked to do something but will have to be asked several times before they do it and then they will go back to their room to sulk as soon as they have completed a tiny part of what has been asked. Would you answer change if the child was also acting like this with caregivers outside the family?
