No, it's true. I found it while researching bf'ing when pregnant with my 2nd. I had such a difficult time with my first dc I wanted to learn as much as I could before my 2nd dc.
As I said, it might have been luck, but, I did do an absolute tonne of skin to skin and I did stay in bed for the better part of 2 days to focus on bf'ing at the beginning.
I napped when baby napped otherwise, always skin to skin, plus co-sleeping/safe sleeping would be skin to skin.
I didn't offer formula and I didn't pump. I drank at least 8oz water after every feed, even at night and ate snacks, including high mf yoghurt, at night. I weighed baby daily to monitor weight gain.
I didn't have any issues with supply. Baby was given formula when I went out (1-3 hours at a time) and it didn't cause any issues, either.
I decided not to pump because I honestly felt such an aversion to it after being a slave to the pump with my first dc. And in hindsight it was a complete waste. I had used 3 different pumps, one on loan from the hospital, all good quality, and if I was lucky I'd produce a bottle a day. So my first dc got that one bottle of breast milk and the rest formula. My first dc would fall asleep within a few minutes of bf or just snuggle in and not even try to feed. There were some good sessions as well, but I was certain baby didn't get much because they'd always be very receptive to a bottle right after.
So, like many women I pretty much gave up, not to mention the fatigue with a new born being a new mum.
I also consulted with a lactation doctor , La Leche League, 3 midwives and a doula. So, I had support. I also was open minded to try other things and spending time in bed was a welcome approach. In my research I came across several articles about re-starting lactation as well.
If OP wants to try it there's no harm. Baby actually getting milk would be a bonus. But, the bonding, boost in feel good hormones for both and neural pathway development for baby are benefits that are worth the attempt.
