By 1992, it wasn't 'promoted' to formula feed, but there was no real mention of BF in NHS antenatal classes other than 'We have to tell you it's better. You can get mastitis, go to a sex shop and you can buy a numbing spray to stop your nipples hurting and you'll need breast pads in your hospital bag in case you leak milk in front of everybody'.
There were racks of individual formula available to all Mums on the wards and it took a week to get an appointment with the Breastfeeding Advisor, by which time you'd been berated by the midwives for having a baby crying at night when that could be solved by giving them a bottle and that you were being silly wanting to BF when you'd had a section. All the posters were conspicuously provided by formula manufacturers (and, going by the stickers/painted on logos, a hell of a lot of the ward equipment, such as scales, baths, etc).
The food was shit in hospital if any even turned up for you and it was impossible to get yourself a drink as you weren't allowed to take the baby with you to the day room, but you weren't allowed to have drinks on the ward or to ask a midwife to watch the baby whilst you got some water.
When the BF baby lost weight as feeding started, you'd be subject to 'They've lost weight. What are you giving them?' comments with the unspoken 'this is a Really Bad Thing' lingering in the air and an instruction to come back and wait three hours in a sweaty clinic next week to 'keep an eye on this, as it's not good for them'.
Add to that the Expert Older Parents who would mutter (or shout) about how your baby only cried because you weren't feeding them enough and it's hardly surprising that BF rates were low.
The NCT classes were a bit better as they at least gave the impression it was genuinely the best option for babies wherever possible. And they described the 'American Football Player Hold' for avoiding hurting a section scar, which was the only way either of mine would latch on, even the one that wasn't born by section.
