"Expecting Better" (pregnancy), "Crib sheet" (infant) and "Family Firm" (family dynamics) by Emily Oster. Dr Oster (economics, not md) reviews guidelines, their underlying evidence and talks about alternatives. She provides sensible recommendations (and does frequently support the guidelines!). She is the most quoted in our house, especially the "It can't just work for the child. It has to work for the whole family."
Half hearted recommendation for "Secrets of a baby nurse" by Marsha Pod. Some of what she says is no longer SIDs guideline aligned (it was when she wrote it) but she does clearly have a lot of insight and experience and passes that on well. Her method is very experiential ("This is what works for me") and not study based, but some of her tips have saved my butt (hold your kid upright after feeds!).

Worked for my children. Saved us a bunch of money on diapers as they were both ready and asking to use the potty at slightly over 2 years old.
