I've not written articles about this per se, but things like helicopter parenting and making children play with children they don't want to play with really annoy me (because as you say, there is often a good reason why). I have a Mount Everest of anecdotes I could relay concerning my children's friends, and how some of them have been properly messed up by overprotective interventionalist parents. There is a sensible balance to be struck, as you say.
