My partner and I found that there are a ton of books that often contradict each other or promote fads with no evidence to back up their assertions. So we deliberately eschewed all (parenting) books during baby's early years. This decision turned out to be good for us, we weren't stressed about sticking to the "rules" from one book or other. Instead we listened to our instincts and feedback from the infant under test. Humans have done this for a long time (and it works). Whatever you choose, do give yourself time for introspective evaluation of your parenting and discuss with your partner what you think is working/not working. This can be hard to do after 3 hours of interrupted sleep but it has paid dividends for us.
