So I would like to talk about something that could really help parents (many answers talk about this already) understand their kids and their behaviour. As it would be formed blog like instead of Q-A like, I'm not sure if there's any possible way of doing that (most similar thing I know from here is a openning a wiki or to answer your own question).
Stack Exchange is explicitly not blog-like, and not discussion-focused, and while some SE sites do have their own blog, this is by no means the norm, and in fact the process for creating new SE blogs has been discontinued.
The huge advantage SE has over discussion-based forums is the way writers have to move away from discussion and opinion in order to deliver answers. This is called out by many folks as one of the reasons they like Parenting.SE - a lot of the potential for conflict and argument is removed.
If however you create a blog, you could link to it from your profile, or in chat, and even as supporting evidence in a post. It could not be a link-only answer, though, as those get closed very quickly.
