Elizabeth Pantley gets dozens of e-mails daily about her bestselling sleep book, ''The No-Cry Sleep Solution''. ''No-Cry Sleep'' covered babies up to age two, but many of the parents are asking what to do about older children who are being awakened by a baby's cries, refusing to go to bed or to stay in bed, having nightmares, or getting into the parents' bed at night. This book now provides those parents with gentle, loving solutions to all of the sleep-related problems of children ages 2 through 6. Recent research has shown that kids who don't get enough sleep are far more likely to have behavior problems, be overweight, and have learning problems. But even if that weren't the case, children's sleep problems drive parents crazy. This is the book that will help parents regain time to themselves in the evening and better sleep during the night, without resorting to punishments, locking children in their rooms, and other negative (but common) measures.
