It is possible that the older sibling may be experiencing jealousy towards the new baby. Siblings can sometimes feel resentful or left out when a new baby arrives, especially if they were previously the center of attention. It is important to address the behavior and try to understand the root cause of the older sibling’s actions. It is also important to keep a close eye on the older sibling around the baby and to address any unsafe behavior immediately. It’s also important to have a conversation with the older child and make them understand the baby is a member of the family and should be treated with love and care.
