Correct. I think it’s a stupid phrase, which a toddler is unlikely to comprehend, but I recognise the need to persuade a toddler rather than get into a major set to with them, and have seen and engaged in plenty of persuasion of recalcitrant toddlers in my time.You think telling a toddler that they might put granny at "serious risk" isn't a form of abuse?
There’s a whole back story there that we don’t know, and the poster telling the story presumes a particular conclusion based on their opinions of masks. If I’d been in that position I probably wouldn’t have bothered to get a toddler to mask up, but there are a couple of circumstances where I absolutely would, in excess of the legal requirement.
