German anecdote: A few years ago my 2yr old son seems to have dialed 112 by accident. We learned about this a minute later when the fire department called back to check if we needed help.
It puffed up his chest a bit, but we talked about emergencies, how to get help, why we don't call 911 unless it's an emergency, etc.
I suppose if everyone did it they wouldn't be agreeable, but no one does, so you should too. :)
