The doctor stuff made me chuckle, because I taught mine how to medicate (within reason) in middle school. How to read labels and see which drugs worked for what symptoms and how not to take two meds at once that had targeted the same symptoms - other than Advil/Tylenol. Why? Because my H is horrible with such things, and I worried if I died he’d do something really wrong.
We also didn’t have much money and not great insurance. Going to a doctor was a big deal. So it’s a running joke that if someone doesn’t feel well, I’ll ask them a million times how they feel on a scale of 1-10, followed by a billion other questions trying to figure out when it’s a doctor worthy visit. And by the time we did go, I’d slowly list out their symptoms by day, the meds taken each day, and how they reacted. If for some rare reason I couldn’t go, I’d give H a written list summary to hand to the doctor. And definitely never go to an ER unless you think you’re dying or have a bone sticking out of your skin after hours.
But really, while I tried to teach mine a lot of stuff, remember that you can’t teach everything. Hopefully, you have taught them that they are smart and resourceful and can figure it out. Mistakes will be made, but that’s part of learning.
Edit also remember CC Kids can be a bit different than the norm. I know plenty of adults who have never been on a plane or more than 4 driving hours from home, let alone let their kids do it alone.
