Same, now as an adult, I still stutter a lot around my parents too. My mother explained it as me asking for her attention, telling me this story how this young boy would deliberately get into trouble for his absent dad to beat him because he wants his dad’s attention of any kind—so basically I’m stuttering on purpose(also admitting she’s absent lol) I don’t deny deep deep down I still want her approval, but that’s some gaslighting bs lol
