The book is Introduction to Child Development by John P. Dworetzky (1981) which we picked up from a charity shop for $1. This is by no means a recommendation, just a piece of interesting info.
The table was provided by Thomas, Chess & Birch (1970) and is titled The Stability of Temperaments Over Time. I'll produce it verbatim, so please all grimace together at some of the very outdated anti-bf, very early weaning stuff and all the rest of it that's a bit "out there."

(It means we can blame their dad for anything we don't like. 
I was blessed in my 20s in that I got to share parenting duties with my best friend who was a single mum to at the time a 2yo-5yo. My friend read a lot then and taught me loads which I kept on the back burner. At age 5 her daughter would get up and go into the living room and shut the door and play quietly letting mum sleep in. She is now a very lovely teenager.
