I'd also practise having a 2/3 min shower as I still resent things like no long showers that no one tells you about.
You are so time poor as a single parent you literally have no free time when there isn't something that needs done. I'm not lying. I used to run and I used to read most days.
Now no chance of reading. I'm in bed early every night and up early before dawn and I get woken up several times during the night by baby. Just no free time at all but it shouldn't last forever
After baby finally goes to sleep at night you will have to do all their washing and sterilising bottles if using and the housework before you go to bed.
When you finish maternity it's not as bad but you have to be mega organised and have all your clothes washed in advance as young children need their clothes changed so many times a day with milk and then weaning and then the drooling and the nappy leaks
Also I don't know if you drive but if so...
Look for a buggy that isn't too expensive and will fold up easily into your car boot
I have bought 4 different travel systems including one I had to take the wheels off to get in my boot. Try doing that after being for a walk in a muddy park
So don't spend over 1000 on your first buggy like I did, unless you have an mpv. it was such a waste and you will prob end up buying 2/3 different ones
Also your home will never stay clean again. Children even a single baby crawling around... they are so messy
