You wake up and see you're massive, and also you're invisible so no one can see you, entire planets look like they can be crushed easily by you, but then a mother of a 9 year old comes into view, you then decide to make her be able to shrink her 9 year old kid by kissing her or stepping on her, the mother grows by her kid kissing her, they don't know you did it or even know about their curses, the only way the kid can shrink her mother is by using a shrink ray that you hid somewhere in the house without the kid or mother knowing, they first find out about the curse when the mother kisses her daughter causing the daughter to shrink to doll size, the mother however loves her daughter being so small, the mother looks like she'll want to shrink her kid as much as possible, you then use one of your many powers to let the mother know how she can shrink her daughter and telling her that stepping on her is more effective than just kissing her, you also tell her that if you step on her, she won't die or even be injured, she'll just shrink a lot
