Does this seem normal to you?

I was browsing a parenting website and I read a post from a woman with two children. She has a 6 year old son and a 3 year old daughter who share a bedroom. She complains that she can't figure out why the 3 year old is waking up at 5-5:30 AM every morning. Apparently the 3 year old wakes up early and then proceeds to wake up her son. The boy is not getting enough sleep and it is severely affecting his behavior and performance at school.

She goes on to say that she started putting the 3 year old to bed an hour later every night to try to fix this problem. But she states that at least if the 3 year old is in bed by 6:30 PM she has one well rested child instead of no well rested child.

WHAT?? I told her that I thought she was putting her children to bed too early. I'm also assuming that she was previously putting the 3 year old to bed at 5:30 PM because she says she has started putting her to bed an hour later. The kid is getting 11-12 hours of sleep. No wonder she wakes up as early as she does.

The woman was rude to me and thought that my idea of putting the kids to bed at 8 was ridiculous. I think she's nuts and that she's trying to get too much "alone" time in the evening and is putting her kids to bed too soon. I mean, at 5:30 my family is eating dinner. LOL

Do people normally put their kids to bed this early?
