I have no problems "owning it" if I overreact. It's important for me to model being truly sorry and admitting I could have reacted differently. I call it a do over. My oldest is starting to use the term as a twelve year old.

I have a lot of guilt about the arguments I used to have with my Ex and how our first born would nervously play with her toys over focussing on a toy to try and ignore us. Makes me sad just typing this.
