Also if you are bottle feeding, you can figure out a night routine which will work for the first 3-6 months, assuming the baby wakes every few hours. What worked for us was if one person stayed up late, handling any feeding till 2am, and then the other person would wake up early and get the 5am and later feedings. Highly recommend to find some long running TV series that has like six seasons and a movie to watch during these times, since you will spend a lot of time doing this.
