‘Tantrums come in various forms, depending on the child’s age, their temperament and the consistency in boundaries within your home,’ explains parenting coach and occupational therapist Celeste Rushby of www.munchkins.me, a collective of coaches who empower parents to help transform family dynamics for the better. She says that, despite all prospective parents dreading the ‘terrible twos’, tantrums actually begin at between 10 and 18 months.
