When my wife became pregnant, we got lots of advise from friends and family. Some of it you have to take with a grain of salt, as much of it is useless information for you. One piece of advise that I did follow was getting the book Healthy Sleep Habits, Happy Child. This book was amazingly accurate when it came to children’s sleep habits and needs.
You don’t believe me? Check this out. We have an older son, who was 5 when the twins were born. We also moved into a new house the very same week that the twins were born. So were going along, after their birth, getting the new house situated, taking care of all 3 children, and getting very little sleep ourselves. We jumped to the section of the book regarding 5 year old sleep habits and needs, to find something semi-creepy. That section actually stated: “Your 5 year old can have problems sleeping for many reasons, including moving to a new house or the new birth of twin siblings.” Are you kidding me? This book new my exact situation. Like I said, a little creepy.
