Oh, Baby! — Nancy Krulik

Katie is an ordinary third-grader -- except for one very extraordinary problem! She accidentally wished on a shooting star to be anyone but herself. But what Katie soon learns is that wishes really do come true -- and in the strangest ways...

When Katie turns into her best friend Suzanne's baby sister, Heather, things are bad enough. But when Katie, as Heather, speaks to Suzanne, Suzanne thinks that her baby sister is a genius! How will Katie ever explain to Suzanne that it wasn't really Heather doing the talking, without spilling her big secret?
