baby-hospital visits are brutal. It's about 8 hours of waiting (usually in the middle of the night) with a screaming child while staff ignores you and then finally says there isn't a problem.
Recently during a bout of covid my son's tongue was blue and he couldn't figure out what was up. My wife wanted to the go to ER, the doctor said to go to the ER. I said, "no, there's another explanation for this and nobody is losing a night of sleep over this". The next day we noticed the blue tongue happened after taking some blue-colored vitamin gummies.
