Oh for goodness sake! How pompous! (The young woman, not OP🤣)
That said, I got pulled up for using the phrase «good babies» when I accompanied DD3 to an NCT picnic in the park. It was a lovely sunny day, happy young mums, some babies sleeping, some being nursed- a general air of contentment.
When I commented on the «good babies» I was told there was no such thing as a bad baby so I shouldn’t say that.
Hands up anybody else who, like me and I expect most of my generation, who think that to describe a baby as good means contented, possibly placid but generally happy and healthy!
I’ll keep my opinions to myself in future!
