Kaitlyn reflects on her time spent with her monstrous baby sister, and realises that she loves her sister more than she thought. The word ‘Monster’ then becomes a term of endearment.

Kaitlyn is the only child and has full attention and love from her parents. However as the family prepares to welcome a new life, she begins to feel neglected. As she is very young, she could not understand the change in her parents’ behavior and thus, feels threatened by the newborn’s presence and cries her heart out when she first sees her younger sister, baby Kayla. She does not enjoy Kayla’s presence, but Kayla’s smiles and silly antics slowly break down Kaitlyn’s walls and she finally realized the need to love and protect her younger sister when she sees Kayla crying. From then on, they are inseparable and Kaitlyn uses her own ways to show her love for Kayla.
