1. Ordinary things will do. If it is some ordinary toys, or delicious, parents will definitely buy two copies, so it is ok for brothers and sisters to eat or play first.
It's no good if brothers and sisters compete for their things. If you buy something for your brother or sister, you will not be used to it. You must reason with your brother and sister and let him know the truth and problems. Whether it's your own home or someone else's, you can't rob it.
3. Know how to come first.
If your brother and sister get something first, if your brother is willing to play for your brother and sister, you can let your brother and sister. If it's important to your brother or sister, you must teach him the rules and principles of coming first.
4. learn to be modest. Kong Rong gave way to pears.
Regardless of your brother or sister, you should know how to be humble and tell your brother or sister Kong Rong the knowledge of Rangli.
Parents should be reasonable and not blindly biased. Because some parents don't necessarily love one of them, then there will be deviations in gains and losses, which will lead some parents to ask their brothers and sisters and let them not talk about the reasons. It is because of this preference that brothers and sisters get along very unharmoniously.
