I had the same thoughts when my daughter was that age. I'd hear all of the "helicopter parent" talk and try to make sure I wasn't of them. I think little things like guiding your kid on how to find an answer versus giving them the answer to something is the main thing (whether it be schoolwork or a conflict with a friend). Let them get frustrated and fail so they can learn, but still be there so they know they still have your support.
Looking back, the worry was really unnecessary. It's really easy to overthink things as a parent.
Disclaimer: The fact that I chose to comment on this after some of my posts in Angie's OT parenting thread may lead you to question my credibility.
These are some great points - particularly about not overthinking things too much. My kids are 12 and 10, and I've probably swung too far in both directions- too tough at times, and intervening too much at others.
I'd add to the above:
1. Don't worry about doing everything right or great as a parent, focus on avoiding dumb stuff. If you avoid doing stupid things as a parent that you know are wrong, your kids will probably turn out fine.
2. Praise effort and improvement, not outcomes. I try to provide as much or more praise for them putting in lots of time practicing on their own in sports or school as I do having a great game or great report card. Tie the result to the hard work leading up to it.
3. If your kids fight with each other or friends, praise them for de-escalating it and finding a resolution (provided that resolution isn't a terrible idea). On the flipside, I focus my discipline not on an argument, but usually in the fact that something fairly minor escalates into something bigger.
