All About Sam by Lois Lowry
At last Sam, Anastasia Krupnik's irrepressible little brother, gets a chance to tell his own story. From his first days at the hospital, through his Terrible Twos, to his first days at nursery school, we see what Sam is really like. But things are never quite like they seem. In the delivery room, Sam's first words, "Don't drop me," are heard only as "Waaaaahhhh!" And even though he has a perfectly logical explanation for flushing his sister's goldfish down the toilet, no one understands. From training pants to moving day to nursery school, Sam continually tries to unravel the mysteries of the world at large, facing each crisis and adventure head on and responding with his own brand of humor, candor, and naive insight.
