I highly recommend the book "Solve Your Child's Sleep Problems" by Richard Ferber. He is a sleep scientist that has written this very readable book. He explains how to teach a child to self-soothe so that they learn to go to sleep & stay asleep without your help. He also explains how to set a bedtime routine & schedule and how to tell how much sleep your child needs. It is a wonderful resource & has done really great things for my family!
