I recommend finding books based on actual parenting research, rather than collaborative or consensus-based sources. Consensus does not mean truth. There are countless parenting myths bandied about that are based on nothing more than idle blog posts or simple social inertia. Parenting advice is especially susceptible to "feel good" myths which sound like common sense, but aren't actually true. (I've found that most "consensus" advice is just rationalization validating the giver's choices, e.g. saving for college, bedtime routines, etc.)

In my experience, pediatricians often have good advice on relevant books and topics.
