A baby sister!  You have got to be kidding me. Why would Lulu want a baby sister? And she tells her parents that in the form of a temper tantrum! No way will she let this happen. But her parents have other ideas. They are actually sending her to Camp Sisterhood where they will try to get her to accept the new sister. No way is that ever going to work.
