Honestly it can get a bit unrelenting. Best to let a sort of routine evolve.
Pre birth I spent the time sleeping, arranging hospital bag, stocking the freezer.
Post birth:-
Weeks 0-3:- dh home, lots of visitors, lots of discomfort, lots of broken sleep, emotions and hormones sky high etc.
Weeks 3-8:- tired, happy, finding my feet, swing between joy of watching a beautiful baby and guilt of wanting to lock myself in the kitchen alone when dh came home. Out for a walk every day.
Weeks 10-20:- proper routine, for baby and me. More sleep. More structure. Out for walks every day. Maybe a class or meet up proper with other friends and their kids. A night out or two.
Weeks 20-30:- soaking it all up and loving it before returning to work.
I went back to work at 30weeks or so but dh was off for a few weeks before dc started going to childminder.
Habits I got into - making dinner (I wanted the break and to force dh to have 1.2.1 time with dc), home for Pointless starting (5.15pm, I'd make a brew, dc in their bouncer next to me). Walked every day. I even stopped doing a big shop so we shopped for dinner most days. Laundry. Dc liked being out in the garden while I pegged out the laundry taken we would lay under it.
