Cecelia is a clever little girl who can do many things, even write her name in pen. But she has a problem that won't go away: she wets her bed. She doesn't mean to do it! She tries very hard, but still, there are horrid plastic sheets to sleep on and soggy nighties to wash in the morning. Then one night Cecelia has the most wonderful dream, about a little mermaid who reveals that she, too, has had this difficulty.
