I slept with my grandma, mother when I was a child <10. That's because our apartments were super tiny back then in China. It isn't much of a choice. My son is sleep-trained to sleep alone in his room. At first, he would refuse and cry, and he woke up every once awhile, later he just got use to it and slept 12 hour straight. Not only he slept without any distraction (me), but also it is much easier on me as well. Important metric I think is whether the baby sleep enough, rather than style of parenting. Sometimes it is just economic factor.
