I sent 'Go The F*ck To Sleep' to my brother who's wife had twins 6 months ago. It cracked them up. My evil step-mother thought it was horrendous and rang me up just to tell me so. It made my day knowing I'd offended her .
Btw Quatermass, you remember Noni Hazelhurst? Actor and past playschool presenter here in Australia ( for you, non-Aussies). I saw her reading it on youtube. Very funny.
