I love it too!
Usually, in this stage of a story, it gets very repetitive and boring, but not here. What's unusual is not the Mimi-character, I think. Neither is Ally, her annoying sister, of course. There are plenty of girls like them in stories around the DL world. Rather, it's Mimi's mother that's something else: She's insensitive in such a cool and 'natural' way, which makes all the difference. In contrast to all the yelling and/or spanking going on in so many other stories, Mimi's mother is much more subtle, simply using a skewed but consistent logic which Mimi is never, in the end, strong enough to argue against.
Finally, I'm a fan of diaper checks. This story has plenty of them, made by Mimi's mother in any kind of situation, often coming as an embarrassing surprise to Mimi, but nontheless in a very everyday manner; 'authentic' if Mimi was actually a toddler. If you're not following me here, just read once more the part, in this chapter, where Mimi is having her diaper checked while watching tv. Cute and crazy at the same time, I love that!
Thanks for a great story, please continue! (But not just for the sake of it: A nice end is better than a story that loses its spirit, if you ask me.)
