@perfectlove25 I'm DOING THIS CURRENTLY.
Shifts was the thing that worked best for my partner. The first 2-3 weeks she didn't want to introduce a bottle so it was really heavy on her and I just supported her by getting her pillows, haaka, drinks, and changing diapers at night.
But after that we did a 9-2 shift and slightly before. She would do a late feeding and I would stay with the baby as long as possible for her to get sleep away from baby (they are noisy).
I work full time at a very high stress job and this is what works best for us. GETTING ENOUGH SLEEP IS CRITICAL IN HOPEFULLY REDUCING PPD. It's gonna happen in many cases but sleep definitely helps.
I currently do 9-3ish now and then my wife will let me take a bit more time in morning (currently on paternity leave) with a 6 week old. But we will continue shifts.
To be honest, it's the most efficient way of making sure each person gets a modicum of sleep and it's not that bad. You'll get used to the reduced sleep schedule.
You're partner being the sole breadwinner is NOT an excuse from night time activities. (I'm the breadwinner) it's their kid too, you CANNOT take it all and it will erode your relationship/perception of your partner if you try.
Communicate your needs. Please please please. For your sake and your partners. You shouldn't need to carry the whole load. You aren't alone and most men want to be there for their wives but don't know what THEIR priorities are.
Thanks for coming to my Ted talk.
Edit: my wife is really good at communicating now that we have been through the first kid. She had PPD really bad and felt guilt about "being the perfect mom" or "needing a break" etc. That's where my last paragraph was derived from.
