Me and my husband would have a routine for waking up to feed ect
That's great that your husband is an equal partner, so many aren't. If you do go ahead with your plan, I'd advise bottle feeding as, naturally, breastfeeding would mean all night feeds would be on you. It would also make it harder to leave during the day of course.
Also, there is of course the fact that your baby won't have read about your desire for routine, and may well have a tough time adjusting to the outside world. Our DD refused to sleep lying flat at that stage, so she slept on us, and in her bouncer when we were desperate. There is no way we could've cobbled together enough sleep for two functioning adults.
I don't want to seem unreasonably negative, and I don't want to rain on your parade. But having a tiny baby can be So. Fucking. Difficult. And I had friends who had it much, much tougher than me. And that's without considering those whose babies are ill or who have long recoveries from complicated deliveries. And of course, there's no way to predict what kind of baby you'll have.
Talk to any friends who've had babies in the last few years, ask them for their honest opinions and see what they think. I know very few who would've been capable of returning to work or study so soon after having their first (I'm assuming?) baby and I don't think any of my friends would recommend it.
Like I said, women all over the world do manage. Just look at the US and it's crappy maternity policies, it's the norm there. But it's so so hard, and I don't see why you'd back yourself into that corner if you had any other options.
