Teaching patience to your child can be difficult but it can be done. Provide a good environment and show the child by examples. Talk to them even if they don't understand you. This will let you create a relationship with your child. Kids learn by show and tell - ask them to make up stories about being patient. This way you can understand what the child is thinking and develop your training further. Most importantly, adults can be an example.
Why should you teach patience? Teaching patience to a child can have numerous benefits. Being patience allows them to think and act properly. If they don't have patience, they won't have time to think of the logic.
Hope it helps. Cheers.
