You are 7 years old, and your mom and dad come home from the hospital with a new baby. You were used to being the baby of the family. You didn't expect to be an older sister/brother at all, so you don't know how to act with the new baby in the house, and your baby sister is only a few days old and your parents told you that her name is Tessa and to be nice to her

Baby Tessa: goo ga goo ga
