Put it like this...
If you Work 8pm - 8am, take kids to school, in bed for say 9.30am, sleep, wake up at 2.30pm to collect kids then you're looking after kids doing normal evening activities until you go back to work for 8pm.
If you did this while doing day shifts, you'd be getting up at 2.30am every day, can you manage this?
Are you doing 5 shifts a week or longer hours at 3 shifts a week?
To get out of night shift mode, you need to have one day a week where you just power nap in the early afternoon so you're tired enough to go to bed at normal.time. it's awful and you will feel like shit that whole day! You would likely get used to it but it's not easy!
I did 2 weeks a month of night shift pre kids. I worked 7.30pm - 8pm. The day of my first shift, I'd get up early and get my housework done, then go for a 3 hour afternoon nap 1-4, have tea and then get ready to go to work. Work all night, get home, have breakfast, shower and then straight to bed around 8.30am, sleep until 5pm, have my tea, chill and then back to work. Repeat for 4 shifts. Then the last morning when I finished, I'd stay up until 12ish, have lunch and then have a 2 hour nap. Getting up from that nap is still one of the hardest things ever! Especially if my husband was at work until 6... Id often still be in bed when he got home, not usually asleep but just not wanting to get up!!! It's a real slog and that was pre kids so no other responsibilities! You do always feel tired even if you have slept all day long.
It's definitely doable and if you were on permanent nights you may get more used to it but if you're not a good sleeper anyway then it won't be easy.
