I was born in 1977 too - my Mum was a scientist, so she didn't fancy any of that NCT malarkey. She had me in hospital, with an epidural (she still thinks anyone who doesn't have an epidural must be mad - "they're the best thing since sliced bread" apparently).
She remembers being advised to drink raspberry leaf tea near the end of her pregnancy, and to take iron tablets, but there was no recommendations to give up caffeine, or to keep fit. (Unfortunately she's been obese ever since.)
She was only 27, yet clearly remembers being labelled an "elderly prima gravida" by the doctor. And she can't quite believe how much responsibility is given to midwives these days.
She tried to breastfeed and struggled. There was no support, so she did mixed feeding for a few weeks and then switched to formula. With her next pregnancy - twins - she didn't bf at all and that was seen as completely normal.
I was put to bed on my front, and wore terry nappies - under some lovely brown crimplene romper suits, I expect.
And my Mum is fairly sure she had undiagnosed PND - the isolation of giving up work, coupled with the complete change in lifestyle and the bf problems, I suspect. Contrast this with my experience, where as soon I as told the HV I was 'reaching the end of my tether' trying to get DS to nap in his cot during the day, she leapt on those words and practically tried to have me sectioned.
That's what changed, she reckons. Apparently everything else is much the same.
I'm sorry your Mum's not with you any more. Pregnancy made me want to connect more with my Mum, too. Could you talk to an aunt or one of her friends about this?
