I think my parenting has become naturally more UP like as mine has grown older. So did my parents'. And no doubt my grandparents'.
Not because of any special philosophy, just because it makes more sense to have more discussions and leave more decision making to people who are mature. And I do enjoy discussions with my pre-teens, they're great fun.
When they were little, I felt responsible. If their teeth rotted, it was my responsibility. If they didn't go for the eye test and their eye sight deteriorated, it was my responsibility. I couldn't, just couldn't turn round now to my 12-yo and say, yes it's tough that your teeth are bad/your squint never was corrected/you had horrendous chilblains when you were 4, but it was your own choice. Because I know she would now blame me and think that was unfair. (I grew up in Sweden where being allowed to go out without appropriate gear would probably mean that a few of my fingers and toes would be missing by now). However, I am more inclined to let her take the consequences of her own actions now.
Also, I am less tired now. Older children are less tiring. And personally I think it is perfectly ok to make the occasional decision simply because Mummy is tired and doing it your way will make Mummy even more tired.
A lot of the time the consequences of their actions are suffered not by the children themselves but by other people. A child who has slept in the same smelly clothes for the last week may be as happy as can be, but other people may not. A child who likes throwing stones is not going to be popular- but they may be having a whale of a time.
Peer pressure is a powerful enough influence on my 12yo to keep her a pleasant sight/smell to other people. It means she is considerate to other people. She is mature enough to feel empathy with other people and try to make their lives more pleasant. But that didn't work when she was 4. Doesn't mean I think other people should have been inconvenienced.
I also insist on things like a 7yo offering their seat to the old arthritic lady on the bus (after I've already given up mine to the pregnant mum); her aching joints won't care if the child is doing it for the wrong or the right reasons; she just needs a seat. Some things just need to be done.
