If you're used to getting six to eight hours of sleep a night, know from the beginning that you probably won't be getting them in one long chunk but rather sporadically throughout the day.
"Every three months after the baby is born, there will be a shift in sleep, up until 18 months. That's a year and a half of your child changing their sleep patterns. Some babies sleep really easily, others don't. Some people sleep train, others sleep with their children," says Slocum. "There is no right way to do it, but making sure you are getting the correct amount of hours you need can really help you feel more present and at peace. This may mean that you nap when the baby naps in the morning and are still in your PJs until 1 p.m." And that's OK.
