Tomorrow is Earth Day. If you would like to observe it with your youngsters, here are some books recommended for children by the editors of The Horn Book Magazine and The Horn Book Guide. The editors and reviewers are librarians, teachers, booksellers, authors and artists, who receive about 3,500 books a year for review.
* "Cartons, Cans, and Orange Peels: Where Does Your Garbage Go?" by Joanna Foster. Ages 8-12. $15.95. This book provides clear explanations of the problems and processes of waste disposal. Manufacturing and other industrial activities are discussed, but the focus is on a more personal level: the waste material that accrues in the family garbage can.
* "Dinosaurs to the Rescue: A Guide to Protecting Our Planet" by Laurie Krasny Brown and Marc Brown. Ages 4-8. $14.95. The Browns' popular dinosaur characters return in an environmental guide that encourages children to "use less, use things again and give something back to the Earth." The book gives specific -- and enjoyable -- ways children can help.
* "Red Leaf, Yellow Leaf" by Lois Ehlert. Ages 4-8. $14.95. A young child details the life cycle of a sugar maple tree.
* "Sea Otter Rescue: The Aftermath of an Oil Spill" by Roland Smith. Ages 10 and up. $13.95. This book explains the impact of the 1989 Exxon Valdez accident on the sea otters in Alaska's Prince William Sound. The events that led to the spill are summarized, and the author details the otters' rescue and rehabilitation.
* "The Old Ladies Who Liked Cats" by Carol Greene. Ages 5-8. $14.95. The delicate balance of an island community is upset when the mayor decrees that all cats must be kept indoors. He learns that the cats chase away the mice who eat the bees' honeycombs, keeping the bees from pollinating the clover that the cows need to produce milk.
* "Window" by Jeannie Baker. All ages. $13.95. The ways in which human beings change the landscape around them is the theme of this wordless book, which shows those changes from one child's bedroom window.

Diapers and day care
Reusable cloth diapers are fine for your baby at home, but in day care settings, the health benefits of disposable diapers are a big plus, according to the Diaper Manufacturers Group of the American Paper Institute, citing guidelines issued by the American Academy of Pediatrics and the American Public Health Association. Those guidelines call for using disposable diapers to minimize contamination of care-givers and other children.
* "Becoming A Winner." Clinical psychologist and radio personality Dr. Jim Dassinger will talk about healthy ways to manage stress and develop a positive attitude during the final lecture in The Joannes Series for separated, widowed and divorced people. Sunday at 2 p.m. at Mercy High Schoool.
Preregistration encouraged. Call 433-8880, Ext. 23, during school days. $4 donation. Child care available for those who request it by tomorrow.
* "Romance and Love: Two Opposites that Confuse Our Relationships." Dr. Mark Stephen Komrad of Sheppard and Enoch Pratt Hospital will discuss how the ideals of love and romance can sometimes get in the way of meaningful relationships. April 28 at 6 p.m. at Chizuk Amuno Congregation, 8100 Stevenson Road. $12 includes a kosher dinner.
