Last night during a phone call with 20 year old DS we were trying to remember the name of a picture book I used to read to him when he was little. All we could remember was one line said by one of the characters, possibly a bear, possibly the main character. It was "It won't last, it'll be gone by morning" and about snow. We kind of think the bear(?) was a bit of a sad character but really that's all we've got. Can anyone help? It is driving us mad!
