Chicka Chicka Boom Boom, by Bill Martin, Jr., illustrated by Lois Ehlert
Other alphabet books pale in comparison to this catchy-beat classic, in which the letters scramble to race each other to the top of a coconut tree. (''A told B and B told C/I'll meet you at the top of the coconut tree.'')

Mrs. Mustard's Baby Faces, by Jane Wattenberg
There are no words on this ingenious, strikingly simple accordion-style book, just pictures of babies' faces — happy on one side, sad on the other. Yet looking at other babies, as this book proves, somehow keeps infants happy and engrossed, usually long enough for Mom or Dad to make dinner.

Pat the Bunny, by Dorothy Kunhardt
When it was first published in 1940, Pat the Bunny — one of the first interactive books — caused a sensation. All these years later, it no longer seems quite so remarkable, yet its sweet, simple appeal — looking into a mirror, touching Daddy's scratchy face — still endears it to toddlers everywhere.
