The booklet, written in Spanish, is intended to help parents of babies with cleft lip and/or cleft palate. Topics covered include the sequence of prenatal development and the effects of birth defects, common misconceptions about what causes the conditions, possible hereditary and environmental causes, and what it means to have a cleft palate or a cleft lip. Drawings and photograhs depict the result of surgical repair. Parent concerns about eating problems, and the effect of the condition on speech, intelligence, hearing losses, and teeth are addressed. The final section discusses the ways in which cleft palates affect children's personalities. (CL)
