My son is about to be 6 years old. He is single child . From childhood ,he used to show off Tantrums . We resisted as much as possible to give him everything. However with increasing age his tantrums are not decreasing but increasing. He doesn't want to hear No. This happens more often at home and he becomes normal outside home.We fear this might lead to bigger problems in future.We do not meet his demand everytime but still that is not ensuring his behaviour change. Not sure how to deal with this.This also keeps us tense .Is there a consultation process which can address this ? Whom should we meet for the same?
