So I do like the aspects you mentioned very much.
I normally play little one but can be both little one and a caretaker if you be one for me too.
How old do you like your character to be? I do like to play around 7,8 but can change.
My caretakers have to be male and preferably from a fandom I like (but it's no must to know them)
Setting would be prefered to be modern of course
I can be a female caretaker for you of course.
