The vast majority of parenting advice out there is sanctimonious BS pushed by people who are either following a fad, using it as a way to establish themselves as some sort of in-group, or with some commercial motivation. For example, breastfeeding and sleep training are a minefield of guilt-tripping and unsubstantiated strongly held opinions. (If your partner does end up breastfeeding - which is by no means necessary - I do second the advice to have a few emergency breast hand pumps available. Also, in the US the hospitals push these giant awful Medela pumps - they are completely outclassed by https://babybuddhaproducts.com/).

Emily Oster is the one author I'm familiar with who comes close to countering this trend, but even she gets too prescriptive sometimes.

The basics of parenting are very simple in theory and pretty hard in practice - stay available, stay patient, stay positive, divide and conquer tasks with your partner, take enough care of yourself to enable the above, adjust as needed. There's not much that's universal beyond that. Your kid's experience will be highly personal to your kid and you'll want to look at the tools and resources available to you (ranging from nannies and food service to bottles/bibs/furniture) and keep evaluating what's working and what's not.

(Also second the other comments referring to miscarriages. They are much more common than you might imagine, and of course incredibly challenging in part because they're so hard to discuss.)
