We all have a natural instinct to protect children from harm. It's never fun to see a child hurt, even if it's just a scraped knee. But on the other hand, children need to take on physical challenges to learn and grow, and scraped knees and other bumps and bruises teach them valuable lessons about their own limits.
我们都有保护儿童免受伤害的自然本能。看到孩子受伤从来都不是一件有趣的事，即使只是擦伤了膝盖。但另一方面，孩子们需要接受身体上的挑战来学习和成长，擦伤膝盖和其他磕碰和瘀伤教会了他们关于自身极限的宝贵经验。
