Little Cherub says "Ooff!"

Little Cherub's new literary fixation is this Farm Animals board book, which has to be read umpteen times a day. It is DK style, with clear photographic pictures and minimal text. She isn't interested in the text anyway, just in what noises the animals make. We have now moved on from "That's a cow. Cow says moo" to asking her what the cow, sheep, dog and so on says.

"What does dog say?"
" 'Ooff!"
Triumphantly.

I am being bashed insistently on the knee with Farm Animals as I type.
