"Getting Rid of Me" Volume 7 from Conversations with My-8Yr-Old-Me talks about "Baby-Girl" learning how to find a healthy 'grown-up' way to "do the math" so that bedtime doesn't feel like everyone wants to get rid of her.
Another fun adventure with "Baby-Girl" and "J.E.L." with a time-line at the end to create your ((own)) math for bedtime.
A link to watch the author read the story and explain the time-line is given in the book.
