Not sure if you mean for a toddler or just starting up.

I am having my (first) baby soon and instead of trying to figure out baby books on my own, I registered in some parenting sessions at the local children's hospital. The doctors/instructors there usually have the most up to date practices/references and other (local-)specific resources. I would recommend checking those out.

Most books will talk in generic terms, they (doctors/instructors) tend to get really deep on things which can be awesome.
