The book is called Babywise by Gary Ezzo. It has been published, re-edited, re-published multiple times due to medical misinformation (and yes, it states swatting a 6 month old baby for 'misbehaviour' at the dinner table). I've read it myself when I was pregnant and looked online for more information because something just wasn't right.
This is an article written about it, by an actual doctor, because Ezzo is not even a health professional.
