Children need to clean up their own mess both at home and elsewhere. Whether they are playing at home or at a cousin’s or friend’s house, teach them to pick up their own toys and mess before they leave the area.
Teach your children to eat with their mouths closed. The munching noise and weird faces may look cute to you, but not so much once they outgrow the cute stage, and to many others it will be considered bad manners.
Children need to learn to knock on the door before marching right in. At home we often do not care for such courtesies which eventually lead to bad habits and a bad outcome in public situations.
Children should be taught to cover their mouth when a sudden sneeze sneaks up. Often we are unprepared, yet we habituate ourselves to be civilised by putting a hand over our nose to somewhat conceal the sneeze.
Our culture hardly teaches us to say “thank you” or be grateful in any way. Teach your children to respond with a “thank you” in most places. Thanking someone does not in any way mean belittling yourself.
Children like interrupting other people’s conversations. This is a habit that lingers with them even after they have grown up. This is why you must teach them from a young age to not interrupt in between another person’s speech.
When in public try not to pick your nose or scratch yourself in weird places. This is something one should always warn their children of as nose-picking seems to be second nature to most children.
