YTA. Quite frankly, I quit reading after “Not for any particular reasons, they are not naughty or anything, but I feel I’ve been there and done that with my own children and previous step children.” THEN WHY ARE YOU DATING AND LIVING WITH A MAN WHO HAS CHILDREN???? Wow, you’re just a real piece of work. You’ve already done it with your kids…and apparently plenty others…so this poor FOUR YEAR OLD deserves no warmth nor love in your home from you because….what? You’re bored? Get your life together and get out of this man’s life. That child didn’t ask to be brought into this world and they sure as shit didn’t ask for Cruella for a step mom. Yikes.
