Book excerpt: Pediatrician Sandy Chung finds that new parents have so many questions during the first weeks of their baby's life. What's normal? Is my baby okay? Am I doing this right? Her book presents answers in an easy-to-read format, loaded with illustrations and photographs. Topics include how to give a sponge bath, using that huge nasal suction device from the hospital, rashes, birthmarks, and much more-all the issues that affect babies up to one month old.
