A comfortable, ordinary guide to the medical problems of childhood--arranged first by age group, then by body system (with extensive cross-references). Thus, parents needing reassurance on a specific, immediate problem (""Yellow-White Pimples on Splotchy Skin"") can flip to the appropriate age/system section (The Newborn/Skin, Hair and Nails) for information. Read straight through, the text brings up hundreds of major and minor problems that parents may never have thought of (lopsided mouth when crying, technically called hypoplastic depressor anguli oris muscle); but pediatrician Simon is reassuringly relaxed throughout. On ""asymmetric chest wall,"" he acknowledges that quite often ""the lower ribs may flare out on one side and be perfectly flat on the other""; still, ""there's no importance to minor asymmetry. Nobody's perfect."" Simon is clear, however, on when to seek help. Fine as a fast reference to physical problems--but far outclassed by the more comprehensive guides of which Penelope Leach's Child Care Encyclopedia is the standout.
