First, many people are ... let's politely call it arithmetically challenged. They won't understand how to compute the amount and then obtain the correct dose. A chart or a table might have more success than a formula, no matter how simple the formula.

Then again, the dangers of paracetamol overdose aren't high (and I would think it's less for children than for adults). It's typically only needed for a few days. Perhaps that's where the stress should go: stop as soon as you can.

Paracetamol is the most common cause of liver failure in the US. Its toxicity threshold is somewhere around 4g/day for an adult.

I remember that my wife once bought an over the counter cold drug in Italy that had > 1g per pill.

So we should be aware that it's very easy to overdose this particular drug.

Depends what you call "high", but the risks are far higher than most other drugs relative to availability.
