Lots of good advice.
I was so lucky, I had a lactation consultant, which was great because I was otherwise useless 😂.
To me the most critical thing was The Latch. There were times when I'd disengage DS's poor latch 6 or 7 times in order to get it right! (Little finger between his mouth and my boob to break the suction, not 'just pull!).
A good latch has a good 1/4 to 1/3 of your boob in their mouth!
Let-down is a bit odd to start with, as someone says, like a short electric tingling, but it was a great boost, knowing I was 'doing it right' in getting let-down.
DS2 was a stroll in the park, instant perfect latch, tho I also knew how to position him!
The cream sounds like a good idea. My experiences were 2 decades ago, and I don't recall specific creams, but I did use Savoy cabbage leaves, as suggested!
Don't expect it to be a stroll in the park, it does require a bit of determination; and if it doesn't work out, so what? But success means easy on demand feeding, no expense, sterile bottles or formula.
Oh, and don't drink litres of orange juice when you're feeding. Colic on a stick.
