Mothers out there !

So for about 2 years now i been not judged by my mother and father but they like expressing the way they raised us ( my brother and i ) and how i am raising my son . If there's one thing I'm confused about is since my son was about 8 months i tried putting him on a sleeping pattern and now that he's 5 on the weekdays because we work a lot and early he's in bed every night by 8:30 plus it gives his father and i sometime for us at night . My mother i guess you can say judges me for that saying i put him to bed to early and that its my fault he's up by 8 in the morning on my days off ( which by the way i don't complain he's up at that time ) . So am i wrong for having him on a sleeping schedule?
