Can we add in the licensing angle?

Even informal babysitting, I wouldn’t want to touch, in today’s society, without some professional training and certification. Things like CPR certification, food safety inspections, safety imspections etc. Keeping someone’s child can be great informally, but let something (and we all pray it doesn’t) happen on your watch and people get justifiably upset, so cover yourself before even taking on the chore professionally/semi-professionally.
