It seems that nowadays we have an extremely interventionist culture, and it leaves us ill-equipped to recognize situations where the best thing to do is nothing at all.
It's not just around child-rearing. I have chronic pain from a decades-old sports injury, and well-meaning people frequently advise me to get surgery to fix it. There's a tacit assumption that, by choosing to live with it, I'm simply being complacent. (There's also, for that matter, a tacit assumption that an appropriate procedure exists in the first place.) If I point out that the surgery for my sort of thing tends to have much worse long-term outcomes than choosing not to pick at it, then I'm generally told that I just haven't found the right surgeon. Similar for my nearsightedness - I have one family member who thinks I'm crazy for not getting LASIK surgery. My take is myopia can be effectively treated with an inexpensive and non-invasive device, while LASIK comes with significant risk of causing different kinds of visual impairments that cannot be treated, so the risk/reward balance just isn't right for me. But that's not how they see it. What they see is that I'm just being weak-willed, because I'm opting not to do something when there's something that could be done.
But it upsets me more when it's child-rearing, because then it's adults choosing to screw up the life of another person who doesn't have any say in the matter. Ostensibly for their own good, but, more accurately, I think, because the adult feels like this is how they need to perform their role.
