Tell Me What It's Like to Be Big by Joyce Dunbar (2006)

Luckily, her older brother, Willoughby, is there to help--and to tell her about the many things she’ll be able to do all by herself once she’s big.A cozy sequel to the bestselling Tell Me Something Happy Before I Go to Sleep, this gentle and reassuring story about growing up is just right for every child--big or small.
