Accepting bad care.
The downside of empowering parents to know the difference between evidence-based care and myth-based care is that when they don't have the option of good care at they know it.
But sometimes we do have to accept care that we know is misguided, futile, and just plain wrong. There is a time to be angry about that, to point it out, and stand up to it... but unfortunately, not in the moment. We have to keep focused on the long-term goal: our loved one's life. There are times when being right isn't an asset, and fighting the urge to say so - to howl at the unfairness - is some of the bravest parenting we can do.
Coming off as the meddling, over-involved, know-it-all, angry, over-reaching, pain in the ass parent of the patient is so easy: All it takes is the faint whiff of our disapproval and a few pointed questions. Being THAT parent makes things worse for our kids in too many situations.
Have I done this? Yes. I've also accepted care that even at the time I knew wasn't good. I've agreed to things I knew I had to because I lacked the authority to stay no. I've worked with people that were great on 50% even though they had it wrong on the other 50. I've sat through advice that I knew we couldn't undermine. It sucks.
The time to protest that, to try to fix the system, is later. Holding out for that is worth it, and feels great.
