In the unlikely event that she is, you can nod your well-rested head and smile. Take it from this mother of 11, both of you will. For now, though, don't put too much emphasis on your baby sleeping through the night.
Children share the same developmental milestones, but their timetables are highly individual.
Children born prematurely or at low birth weights, as well as those who have difficulty gaining weight, will likely need night feedings longer. These babies' needs must be met. Other babies simply have a harder time relaxing or, once there, maintaining deep sleep. They need more comfort and reassurance. When your baby needs a little cuddle in the night, give him one.
