Hi, my LB is 5 he’s pre verbal and only really uses echolalia to speak. He’s started using bad words. I know he knows that they are naughty words because he looks at me mischievously while saying them and smiles when I tell him off. I’ve tried telling him “no naughty words” now he just says “(f### no (name) naughty word) 🤦🏻♀️ I’ve tried ignoring him and giving him no reaction but he then thinks it’s okay to say them and will say them more often. Bad words are the f word (I admit he got that from me) idiot and hate you (from his older brother) I’ve also tried a sticker chart but he has zero interest in them
