Firstly, nature is brutal, and a large proportion of infant animals die as babies.
Secondly, I believe there is some connection with folic acid and tongue tie, so whilst its great for reducing NTD's, and is totally worth it, it may make feeding more tricky.
I think sometimes we can overthink it as well. Animals have no books, ot lactation consultants. Some may have seen family members breastfeed (especially primates) but many will be going on instinct alone. I wonder whether humans are so 'developed' now that some of our instincts have been surpressed.
Weirdly, I accidentally breastfed. As I didn't want to do it, I didnt read anything about it, didn't attend classes, had zero 'support'. No one in my family breastfed. Baby insisted, refused bottles, and I ended up feeding her for 3 years. She just took what she wanted, and I was very passive in it all. From what I know of animals, in many its the baby not the mum that initiate feeding/latching etc, and if the baby can't, then it sadly dies.
