Just the boob thing.
Frankly I don't see there being a huge uptake among those not.. otherwise.. motivated.
sure, feeding my second was easy, but my first - sore/bleeding nipples, rock hard or leaky boobs, night wakings - it's not all blissful cuddles watching box-sets (although, TBF, once we got the hang of it, there was a fair bit of that)
Seems to me that they're just seeing the finished product, and not thinking about what it took to get there. Much like babies in general really.
