Dr. Sears, you and your wife have eight children. What kind of sleepers were they?
The first three were easy sleepers. They slept alone in the crib. We were young parents and part of the crib-and-cradle set at that time. We thought that was the norm. Then we had our fourth child, Hayden, who we call our 'high needs child.' We wrote a whole book about [high-needs children] called, Parenting the Fussy Baby and High-Need Child. Our daughter would not sleep in her own bed. I still remember the night 22 years ago when (my wife) Martha brought Hayden into our bed, and she said, "I don't care what the books say. I have got to get some sleep." She then brought Hayden into our bed, and they nursed happily ever after. Martha slept better. Hayden slept better. I slept better. It opened up a whole new world.
