Guide children correctly
When children's behavior consciousness is wrong, parents should guide them correctly, let them learn to share and learn humility, but only if the children are willing.
Contact with new things
When you meet children who don't want to share, you can try to divert their attention, expose them to new things and divert their interest. At the same time, don't think that being unwilling to share is a bad thing.
Relatively fair
Parents should deal with problems fairly. Older children should not always take responsibility. They also need to learn to distinguish right from wrong, admit their mistakes and correct them.
