Respect children's privacy
The children's room is their world, where some precious things and secrets are stored. Knocking on the door not only respects their privacy, but also shows that you care about their feelings
Avoid accidental fright
The children may be absorbed in their homework or playing games, and your sudden intrusion may scare them. Knock gently on the door, give them a psychological preparation and avoid unnecessary tension and anxiety.
Cultivate social etiquette
By knocking at the door, children can be taught how to respect the space and time of others. In this way, they will become more polite and considerate when interacting with others.
Protect children's safety.
Sometimes, children may forget to close the door or leave it unlocked, which may bring security risks. Knocking on the door is also a way to remind them to pay attention to safety and always be vigilant.
