The news of a baby tends to bring joy to a family. But for one little boy, the idea of a future brother or sister leads to a lot of frustration and an adorable lecture. In the video above, a young boy gives his mom an earful after she announces that she's pregnant. Noting that the news is "exasperating," the boy worries that his parents won't love him as much once the baby arrives. Despite his mother's reassurance, the boy still isn't happy about having another sibling. His sister, on the other hand, seems thrilled with the news.
