A two year-old three a tantrum when she saw her newborn sister enter the house with her mother. She started yelling and crying, her father asked her “Hey Piper, do you like your new baby sister?” and she shouted “No!”. Then he asked “Do you love her?” and she was furious as she shouted “No!” again.
Piper was not giving up on her tantrum as she continued for a while, she rolled around on the floor and yelled. Her father just allowed her to get her anger out of her system until she was ready to accept her newborn sister into the family.
