I don’t get what there is to judge about a 6 pm bedtime or why it’s so incredible to so many people. My 3 year old often goes to bed at 6. Her bedtime is 7, usually, which is the latest that peds suggest kids go to bed to prevent all sorts of issues. If my kiddo has a long day she goes to bed at 6 because she needs a solid 11-12 hours a night (or more) and will not sleep in. It’s odd the bedtime has changed from 9-6, but I don’t find a 6 pm bedtime anything to judge. 9 for a three year old is apparently unhealthy, and I’d be more likely to wonder why she was up that late than the other way around...
ETA: I actually didn’t mean to quote you, Napoli, sorry. I can’t seem to make my wonky phone delete the quote. Apologies.
