First of all, parents should let their children learn to share and learn to be polite.

Parents are fair to their children even in their hearts, but in reality, it is difficult to be absolutely fair because of the individual differences of children. Therefore, in order to promote the harmonious coexistence between the two children, parents should let their children learn to share and learn to be polite.

For example, two children compete for a toy, and neither of them will retreat. At this time, parents should not be partial to any child, but should let their children learn to share, such as playing together, or playing after you finish.

In addition, parents can't always ask for "big concessions".

When two children are in conflict, parents always tell the older one to let the younger one, which can easily cause great dissatisfaction. The correct way for parents is not to tell their children humility directly, but to tell them why.

Finally, after having two children, parents should not forget to exaggerate their children.

Older children brag a lot. Over time, they will take care of their babies as their mission and learn to take care of them with adults.
