Can you remember

How and what age you were sleep trained? I read that each culture has its own definition of appropriate sleep habits but I wonder where most people in our parents generation stood on this issue.

I remember sleeping on a sofa-bed in the same room as my parents for the longest time. I got my own room when we moved when I was 10, but I think it was mostly because my parents’ furniture took up all the space in their room. my mom can barely remember how she sleep trained us kids. As far as she remembers, we co-slept and breastfed as long as we wanted.
