Children like to show off their toys in front of them, probably because they feel the excitement and pride brought by toys. However, if children are unwilling to share toys, it may be because they think their toys should be enjoyed by themselves, or they don't quite understand the meaning of sharing.

Here are some suggestions to help you deal with this situation:

Encourage children to share: First, you can encourage children to share their toys. You can make some sharing rules with children, for example, you can only use toys when no one is using them, or sharing toys can bring fun to other children.

Lead by example: children often imitate their parents' behavior. So you can lead by example, share your toys with your children, or make a list of shared items with your children to let them know when to share them.

Give your children choices: When you encourage them to share, you can give them choices. For example, you can ask children whether they want to share toys with other children, or let them decide when to share toys.

Understand children's feelings: Sometimes, children are reluctant to share toys because they feel uncomfortable or nervous. Therefore, you can try to understand children's feelings and encourage them to share.

In short, educating children to share is a long-term process. You need to communicate with your children patiently, provide them with correct guidance and help them learn to share and respect other people's property.
