Correct them with love. Point out what they did wrong, what their wrong actions has caused and how it can be fixed and also Tell them why it's not good to repeat the same mistake. Take for example, your child beats another. Point out that beating other kids isn't nice, show them that beating the other kid caused the kid to cry, tell your kid that he/she can fix the mistake by hugging the other kid and verbally saying sorry. And lastly, remind them that it's good to be kind, and not repeat the same mistake.
