We have a new baby in church. Now, as it's never too early to start a child's library, I bought him The Story of the Little Mole who knew it was None of his Business.
Daughter introduced me to this book a few years ago and since then I've bought it for every new baby - or at least those whose parents I knew wouldn't object.
It's about a little mole who wakes up one morning to find a pile of poo on his head. He sets off to find out who was responsible. He asks the seagull if it were him; the seagull says, 'No, this is how I do it,' and proceeds to demonstrate. And so on. All the animals Little Mole encounters show him exactly how they do it.
It's great fun - children love anything to do with poo or bottoms - as well as being educational!
