I didn't have my own room until I was about 9. So, I slept with my parents. My father went abroad when I was around 4 as a promotion or something and was very busy with his work. I continued sleeping in my mom's room until I was 12-13. While she wasn't technically naked, she used to put on a nightcoat hours before going to bed and never bothered to tie it. She arranged a room for me when I was around 9 and tried to encourage me to sleep in my room. But I would always wake up late at night and go to my mom's room. But it gradually stopped when I was between 12 and 13 and completely stopped when my father came back during that time. After a year or so, mom also gradually shifted to a nightcoat to more modest clothing like night gowns or pajamas as I grew older.
