Thanks. This is a bit terrifying...and that's just the beginning.
I don’t just mean advice you read on HN, but any and all advice. Advice from friends and from your extended family. Even advice from your health care workers. Every baby is different and what works for one child wouldn’t work for another. So by all means listen to suggestions people might make but don’t stress if you end up doing things completely differently. As long as you show the child love the rest is just an implementation detail.
When they get their second they realise that all children are different.
