Anyone who has lived with young children or talked to new parents can agree that one of the biggest milestones in a child’s life, or in your own, is when he starts to sleep the whole night. Every sleep-deprived new parent rejoices when they can sleep for periods longer than two hours at a time. Very few are lucky enough to have a young child that quickly adapts to sleeping the whole night. Many times parents are key in helping the child develop good sleeping habits at an early age.
