A reassuring book (Sleeping Like a Baby: A Sensitive and Sensible Approach to Solving Your Child's Sleep Problems, by Avi Sadeh) describes the sleep problems of infants, dispels myths about their cause, offers interesting facts and outlines treatment possibilities.
Among other things they recommend that parents "should foster the bond between the child and the father", as this greatly helps in preventing a child's sleep difficulties. Mh, great excuse for Mommy.
