I breastfed both my DCs - over thirty years ago, mid seventies and l do remember it being encouraged at the time, l certainly dont remember being discouraged put it that way. My eldest stopped at 6 mths, when l started giving her solids and she wasnt interested after that and l vaguely remember (well l am an old gimmer) being told that was the 'important' time - the first 6 months - so not to worry.
My DC2,( late seventies) had to stop at about 6 weeks as l was admitted to hospital for a couple of weeks and in their wisdom they put me on a normal ward, baby stayed at home and H at the time had to take home expressed milk for him. Didnt work out and l got mastitus and was in agony plus was distraught at being seperated from baby DS too , got in a right old state.
There was a brand spanking new mother and baby unit next door that had been opened six months previously , but oh no they put me on a womens post surgical ward full of old ladies, ingrowing toenail surgery etc. There was no reason l couldnt have gone on mother and baby unit as l didnt have any surgery, just obs really. A porter told me 'Oh they never use that it's like they want to keep it for show' 
But they wouldnt budge despite our protests and all the physical and psychological problems l was having from being seperated from my baby. When l got home l tried to resume feeding him but couldnt seem to supply enough and was very uncomfortable anyway so gave up. So not a very good pro-breastfeeding experience with my 2nd DC but a good one with my first. Plus l was very young and not so assertive - l wouldnt have let the former happen now.
l remember MS being around a lot at the time and setting quite a lot of store by her. As others have said, lets hope young mums today take her with a pinch of salt. l think young people today do though, they question even the 'professionals' more than my generation did - and so they should it seems.
I dont agree with her about the sling being extreme ! , the third world thing is ..well you carry on BF for economic reasons surely, not stop ? Plus the thing about weaning at 4 months to get more iron into baby sounds a bit dodgy and more to do with her Nestle connection.
The only thing l agree with her is about the child standing on a chair to BF (four or six yrs old ?) helping himself when required. Sorry if that offends anyone but l just felt uncomfortable at that picture and a womans body still being at the behest and demand of an older child, no idea why, but each to their own. I remember viewing a house with my exh in the nineties and the owners were a young family. The mother, had a young baby and was holding an older toddler about 4yrs old and all the while we were talking the boy kept sliding his hand down her top to get at her breast and then just fumbling about with it under her blouse. Not sure if she was still BFing him aswell. She didnt attempt to stop him or put him down but she did look quite irritated by this and worn out tbh and kept fastening her button back up when he took his hand out. l couldnt help but think , take back some ownership of your own body woman. My then H said later he didnt know where to look he found it embarrassing but he was a knob.
