Other good books for mothers of small boys apart from 'Raising boys'?

[Shitemum]

This is for a friend who has 4 yo and 2 yo boys and finds them a handful...

Can anyone recommend a good parenting book for parents of boys?

Yes, 100 cocktailrecipes / the wine guide / etc (I have 4, I Know ).

Seriously I always found the Christopher Green books good when the older 2 were littlies, and would suggest those.

lol, thanks!
