When a new baby is brought home to meet the family pet, the animal may not be too happy about sharing attention with the new addition. So it’s understandable that they may experience something akin to sibling rivalry when they are introduced to a new human baby into your household.
This feeling can be minimized by working with your pet before bringing home a new baby. Drastically decreasing attention and frequently scolding, ignoring, or isolating your pet after the baby comes home will likely make your pet feel stressed. If your pet is particularly attached to the mother-to-be, another family member should develop a closer relationship with the animal. That way, the pet can still feel loved and provided for while mom is busy with the baby.
