The first idea is good, but I'd like to change things a little. I like to have it that at least some of them have an actual need for them, and I'd also like it that in Stella's case, it helps bring her parents back together. I'd also appreciate it if you try to write in a more "proper" style, though you don't have to change to more than one line.

My first idea is reality is changed around the girls making them need diapers and making everyone around them treat them like babies and either they could be taken care of by there parents or by who ever is behind the change

My 2nd idea is some kind of powerful spell is casted on Alfea making all the students wear diapers but everyone thinks its normal(accept for the Winx or which ever ones we want to be) and as the day goes on things start changing more like they need to use training potties there lunches become more like ones babies would have lessons become easier and eventually the whole school becomes a pre school and the students are fully treated like babies.

I'm also open to ideas if you have some or would like to add something to one of my ideas.

Tell me your ideas if you please.
