There are plenty of twisteddoodles cartoons in this book, but it's not a book of cartoons. There are plenty of funny moments in this book, but it's not a book of jokes. What it is, is the most honest account of an experience of early parenthood I've encountered. You'll laugh, but you'll also share moments of sadness.
For me it reflected my own experience of the highs and lows of being a parent, and most poignantly reflected some of my wife's experience as a new mum.
If you've kids of your own, you'll enjoy this book - even if your kids are well past nappies and bottles. If your heading into pregnancy, you'll also enjoy it, but may start secretly looking to adoption :) If you have no intention of having kids, it will confirm your sanity in this choice. Basically, unless your a baby yourself*, you'll enjoy this book.
* And that's just because being a baby is no craic :D
