Telling a young child that they are going to be an older sibling is an important event for both the parents and the child. The Williams Family was very excited to tell their young three year old daughter Kathryn that she was going to be a big sister. So they bought a children’s book to explain the exciting news. They had no idea how Kathryn would react, but they definitely didn’t expect her to say something that would leave dad laughing uncontrollably.
