I have worked shifts for years following has helped make it more bearable:
reduce my standards in the house, the level of which of course varies from person to person. For me personally I’d do a load of laundry so it didn’t build up, quick swish in bathroom. Make sure dh is pulling his weight with stuff.
I used to buy my lunch on the way to work - meal deal or similar as I found it really hard to decide what to make if I was tired and end up not bothering.
Loads of people wake at lunchtime after a night shift and those 3 hours is not enough if you’re back the same night. I would deliberately stay in my nightwear, laze around, watch Netflix. Rest in the hope of going back to sleep. It’s tempting to get up and do loads.
conversely on the final night shift you’ll be able to sleep till 6 or 7pm…don’t!! Get up at lunchtime, eat, shower, get some daylight. Go to be early and you may well sleep well.
if you need sleep on a weekend morning when the family are home, try and arrange for them to go out from mid morning for a few hours otherwise you’ll definitely be woken and struggle to go back to sleep.
