I'm a Big Sister! by Ronne Randall, illustrated by Kristina Stephenson (Parragon Publishing, 2005)
As youth services librarians, we are regularly asked to recommend a good book for children who will soon become a big brother or sister. Occasionally, a patron will ask for a book on this subject that has a very positive tone and Ronne Randall's book is one of these. In I'm a Big Sister! Ellie is excited about the arrival of the new baby and her new role as a big sister. Of course, she does begin to wonder what it was like to be a baby - and wishes she could be little again. However, she also really enjoys being able to help with all of the duties of taking care of a baby - feeding Baby, changing Baby's diaper, pushing the stroller...and finding out what neat things are reserved for big kids and big sisters!
