I've started reading a few, but there's a mountain of choice and so far, these books are about 80% fluff. They pontificate like recipe websites, despite having no ads in the pages. I'd ideally like to find a book that goes over:
1. What I need to do
2. When I need to do it
3. Why it's important
4. Absolutely nothing else
I'd especially like to avoid pseudo-science / instructions backed up by no data, paragraphs congratulating me on being a modern participatory dad, and anecdotes.
