Set up a sleep routine. Decide who will get up late nights, and who will early am. Aka who stays up. And who gets up. Its better for both of you to sleep solo for x hours then both of you worry about 24 hours. Solid sleep is most important. Decide based off of lifestyle what make sense. Sleep helps both parents. Sleep helps with postpartum depression as well. Dedicate a sleep routine, I can't stress this enough. Spilt time..don't double time!
