I try to be very aware of NOT providing unsolicited help. I'm a big researcher, and I raised her to be as well, but I resist the impulse to tell her about articles I've read or great websites. First of all, she's probably already read what she needs to read for herself, and second, I don't want to impose useless information on her or any info that might come across as well-meaning but unwanted advice.
Of course, when you're a mother trying to help a child, that line between helping in a good way vs the bad ways you mentioned is fraught with land mines. So I just stiick to asking her if she needs help, providing my availability schedule-wise, and letting her decide if and when she needs me. And trying to listen more than talk.
