If you haven't yet stumbled across Lookybook you should really have a look. (Just click to turn the pages below).
We first found it when we were looking for The Latke Who Couldn't Stop Screaming last December (and you might want to order a copy of that one now to be ahead of the curve for the holidays).
The Latke Who Couldn't Stop Screaming was by Daniel Handler, writing as Lemony Snicket, and illustrated by his wife, Lisa Brown. It was thanks to them that I spent weeks listening to my son pretend to be a screaming latke.
How to Be is one of Brown's solo efforts.
She is also known (and loved around these parts) for her series Baby Be of Use, published by those clever folk at McSweeney's and available through their online store.
