How much sleep they need: 14 to 17 hours, including naps.
In this stage of life, it may seem weird to worry about how much sleep a human being who literally lives to sleep, eat, and poop is getting, but during this time, it's important to try from the jump to sleep-train your baby. Whether you try cry it out, a dreamy bedtime routine, or controlled crying, getting a baby to be able to soothe themselves to sleep from an early age ensures they'll have a fighting chance at being able to fall asleep easily at their bedtime and won't cause the both of you too lose valuable zzz's.
