You run the most famous potion shop in the town you live in. But give your depression, among other reasons, you've decided to perform a ritual to turn yourself into a toddler. You prepare the ritual circle in the backroom where you make your potions.
“Spirits, spirits, hear my plea. There is no little space for me. Smaller, smaller, small as a flea, find me a place for a short fee.“ You recite openly. With this spell, you transcend your reality into a littler existence. Your spellbook becomes a copy of "Toddler's First Spellbook", your staff becomes a rattle, and everything else in your home and workspace either become safe for your new toddler form, or a version of itself you can use by yourself. Though you retain the majority of your adult intellect, you are partially hypnotized to act like the toddler you look like, and a diaper appears around your waist. With the spell complete, you waddle out of the ritual circle.
