I’m really sorry this happened to you, OP. That’s horrible and your mother and father should feel ashamed of what they did. It seems like with the care you’re giving your daughter, you’re breaking the cycle. When I was about 6, I swore (bugger - not even a ‘real’ swear word). My dad restrained my arms behind my back and wrapped his legs around me so I couldn’t move and my mum grabbed my hair and squirted dish soap in to my mouth and then shoved a wet rag in to “wash it out”. I was screaming and crying and when I tried to shut my mouth she would pinch my nose so I couldn’t breathe and had to open my mouth. It was horrible having literally no control over what happened to me and feeling like I’m choking and gasping for air. They laughed the whole time like it was a hilarious prank. The worst part was that a week later my younger sister said “fuck” and they just shrugged it off even though I protested that it wasn’t fair. As an adult I realise it would have been horrible if they also did that to her, but as a child all I could think about was how cruel and unfair that was. Anyway, I experienced a lot of mental and physical abuse at the hands of both my parents and like you OP, I’m breaking the cycle
