My mother was like that. DS was a super early riser and was usually in bed by 7pm (would wake up at 5:30) and she always commented on how early he went to bed. I tried explaining to her that he woke up early no matter how late he went to bed and if I wanted any time to myself in the evenings, he needed to go to bed early. Fast forward to 5 years later when she stayed with my sister who has a 5 year-old who is up until 10pm. My mother called me to bitch about how my sister let him stay up way too late and "remember how nice it was with your how he was asleep by 7 and you had a nice quiet evening"? So I guess you can't win.
