On rainy days, children have to tread water. Are you a parent who forbids children to go out?

It is human nature to like water and be close to it.

This is especially true for children. In the eyes of children, the accumulated water in rainy days is like a gift from another world, full of mystery and novelty.

Children's curiosity can't be limited. Children should be properly allowed to step on it to satisfy their curiosity.
