Thank you so much! I've been trying to find that one for so long.

I read a story a few years back about a girl who accident poops her pants while sledding with her sisters. After that she can't stop thinking about it and starts to envy her little sister who is still in pull-ups. I think at one point she secretly wears one of her sister's pull-ups and wets it. Laer on she gets sick and her mother gets her to wear goodnites to avoid getting out of bed. She gets to explore her new interest in diapers.
