I know this is a serious long shot, but I've been trying to remember the name of a book I read as a kid. I've been searching for the title for a good two months now, and nothing. It involved a very imaginative young girl. At one point, she was counting sheep, and she started to lose control of them. The other parts of the book involved more imagination-based humor and adventures.
I've tried looking up imaginative fiction stories, stories about counting sheep, children / pre-teen books, but I haven't found what I'm looking for yet. Does anyone have any idea what this book is???
