Sibling rivalry can be tough, especially when a new baby is introduced to the family. But what happens when a sibling feels their new pet is just as important as a new human life? In this AITA post, a brother is caught in the middle of his sisters' competing milestones. He travels across the country to meet his new nephew, but his younger sister becomes jealous of the attention the baby is receiving. She adopts a new puppy and demands the same level of enthusiasm from her brother. When he refuses, she becomes angry and accuses him of favoritism. Is the brother in the wrong for not indulging his sister's demands, or is she being unreasonable? Read on to find out.

Sibling rivalry gets furry 🐶👶
Sibling rivalries can be tough, but what happens when a new baby and a new puppy enter the equation? In this case, one sibling is feeling left out and is taking it out on their brother. After generously giving money to the new baby, the younger sibling feels entitled to the same treatment for their new puppy. But when the request turns into demands and passive-aggressive behavior, tensions rise. Is it fair for the younger sibling to expect the same treatment? Or is the brother right to stick to his guns and not encourage this behavior? Keep reading to find out how commenters weigh in on this furry sibling rivalry.
