My Mother Goose by David McPhail*

"A Collection of Favorite Rhymes, Songs and Concepts"
This collection is more didactic than some other nursery rhyme anthology (rhyme about the months, two page spread about getting dressed, ABC pages, transportation pages, days of the week, counting to 10, action words, shapes, colors, ).
It is subtly organized and ends with night time poems and nursery rhymes.  The last poem is especially sweet (but I may be biased since I have two boys!!).
Warning: One poem is about a witch on Halloween.  Don't think babies need to learn about witches. . . then again some of the nursery rhymes are disturbing!
