Two of my neighbors and my best friend all had babies within just a couple of weeks of each other less than 8 weeks ago. All of them have commented on the sleep deprivation that goes along with having a newborn and one asked me when my babies started sleeping through the night. First, I always need to ask what that means to someone because, for some, they mean to have a baby sleep through the night, including feedings, and others mean sleep straight through 10-12 hours, with no feedings.
