Newborns don't seem to know, or particularly care, about the differences between night and day. They just respond to hunger or diaper change needs at any time, especially in the wee hours of the morning. When you're in the throes of this phase, it helps to think of all the sleep training milestones you'll soon reach. Because at some point, your baby (and, by default, you) will sleep through the night.
Even if it seems like a distant possibility now, your baby will one day sleep through the night in a separate bed. No whimpers for food. No random bouts of crying. Your kid will legit be out for the night.
There are, however, several steps in between. Learning what sleep training technique (if any) is right for your family is a big moment. Hey, even just weaning your kid off night feedings means you have one less thing to do in the super-early hours. It's a process. Celebrate the successes and brace yourself for the challenges that you and your baby will face along the way. And even if you face a long night of wailing here and there, remember that you will, one day, get some real sleep again.
