The arrival of a new baby can bring many changes to a family. All this change can be hard for older siblings or in this case, pets to handle. Bex was used to getting all of mommy and daddy's attention before the baby's arrival. When the new baby enters the picture, his sense of security is jeopardized. All the attention seems to go to the new baby. This results in feelings of jealousy and anger and to the illogical fear of being replaced and castaway.
As the days go by, Bex feels loved again and even looks at the baby with interest.
