I'm so sorry you're not able to ask your mum OP
we sound a similar age as I was born in the early 80s.
My mum was in for 10 days, no complications, she says this was the norm - they were encouraged to stay in bed and rest, and given a lot of help/advice on feeding, bathing etc. She says she had planned to formula feed, but was given a lot of support with breastfeeding (she says not judgemental, just encouraging) and she had so much milk she decided to give it a go - infact she had so much milk she expressed a lot to be used by the neonatal care unit, she even kept this up for a while at home! She fed for 9 months, she says once I had teeth that was it, although as solids were started at 4 months apparently it was quite a long time to feed. Feeding was strictly 4 hourly and 10 mins per side only, she had always found me feeding on demand and breastfeeding toddlers really strange as she said it just wasn't advised when she had children.
Dad's were allowed, my dad was horrified by the whole thing and apparently went home halfway through convinced they had left the grill on, and arrived back not disappointed to have missed most of it 
She says the babies were taken at night to the night nursery but I cried so much (apparently I was a terrible sleeper) she went to find me, and took me back with her, then had to stay awake holding me for most of the night, so not very restful! I was a summer baby, but she says they were advised to wrap babies warmly in a blanket despite the heat and put on their stomachs to sleep, so different from now.
She says they got pram, cot etc second hand - pram was a big old-fashioned solver cross type thing, I can remember my brother in it. A lot of stuff was shared round the family, I have a lot of cousins a similar ages, so someone would have the cot of a few months, someone else would borrow it, then it would eventually come back for the next baby. Apparently she shared maternity clothes and even nursing bras with her sister and sister in law, not sure how this worked as they're all very different sizes! She was in a one bed flat when I was born so I was in with her and my dad until they moved.
Wishing you all the best with your newborn.
