I think this is the main point - all babies are different and OP won't know what kind she has until s/he's here.
It also really depends what kind of work you are doing. Anything where you need to speak to others on screen or phone can be problematic because you can't be sure when the baby will wake or make a noise.
Totally online work which is self-scheduled is easier to manage as you can fit it in around other things.
Posters who can't even get to a shower for the first three months probably have more demanding babies, or they are taking shorter naps.
I was lucky that my DD did nap for 1.5 hours at a time between waking and needing feeding/changing etc. And I only had to do four hours of work a day.
It was still possible to do that, and get showered, and get play time and outside time, and make dinner for the family. I did ask DH to step up and do more laundry, gardening etc.
As I mentioned in a previous post I started back at work when she was four weeks old.
It's very hard work though.
@Gem2x87 my advice would be see if you can get extra work done on the days you are in the office so your workload is lighter on the days at home. You will have to do some work in the evenings and at the weekends so your DH needs to be on board.
Have some backup options that you can call to come and help you in your house when you have a deadline and the baby won't settle - your Mum, friend, babysitter etc
Outsource as much of the rest of life's chores as money will allow - cleaners, gardeners, food prep, laundry. Anything you can pay someone else to take care of don't hesitate. You will burn out if you try to do everything.
For later months when crawling and walking, I created a big system of baby gates so that there was the option for her to be within a safe space just to the side of my desk, and a place for me to work with my laptop inside the gate system so she could reach me too - with places to sit, lie down, I had baskets of different toys and books which I used to swap in and out to pique her interest and give a little variety.
Modeled after what's called a 'YES' space - interesting to explore but safe.

However, maybe I was lucky - DD was very good at playing independently from very early on which have me chunks of time - 20 mins etc to get a part of a project done in pieces.
