Hey parents of young children, want your kids to be not so loud in public places? Here's an idea. Speak quietly to your child. It's called modelling.
My wife and I (okay, we only have one child, but we have a combined 70+ years of primary teaching experience) have observed this is phenomena in restaurants, train carriages, waiting rooms, shopping centres, etc. Parents speaking
at the top of their voices to their sprogs for no good reason.
My theory is you are announcing to those around you what a caring, inclusive and totally cool parent you are.
Why not talk in conversational tones? They wonder why their kids shout, scream and squeal continuously.
Well that's my grumpy old fart rant. Comments?
