We found this in our local bookshop and had a quick look through. I thought it was rather funny so it came home with us.
There are a few mentions for mumsnet: m is for mumsnet and u is for unreasonable.
The illustrations are simple but effective at conveying the message across. It's a very funny take on modern parenting. If you'd like a giggle it is a book to pick up. Nate thinks it's a story book for him and we have read him the book a couple of times while giggling but the jokes (obviously) go over his head.
