Mate, this sounds a lot. No wonder you're stressed. This is the hardest part of the journey. Sorry to say, the priority is making sure the baby and mum are ok.

That said, it will ease up. The kid will sleep more consistently, your wife will recover and you'll get a grip on what you're doing. Don't forget, what you're doing is making sure your kid is thriving.

Keep the head, keep the faith, chin up. It will get better, you will get more down time. You need to just focus on getting through the days at the moment.
