The following are basic manners that your child should learn and use correctly:
Make sure your child says “please” and “thank you” when asking for anything from another person: Prompt your child at all times, until the use of polite requests becomes second nature. Repetition works in this case.
The way you interact with people is what your child uses as a model for appropriate behaviour. Be kind and considerate yourself when interacting with people and your child will learn to say the right things in company.
Help your child realise that actions have an effect on people. Teach your child that negative actions will upset and sadden people and that kind gestures are appreciated.
Do not expect your child to behave perfectly when tired or feeling sick.
Complicated table manners and social graces are beyond your child's ability for now, so don't be too strict or hasty in teaching manners.
