As a parent, you often worry about your child getting hurt, and you do everything in your power to prevent it. One thing you may be forgetting, though, is that injuries are often not as bad for children as they are for adults. Kids really do heal faster in many cases.
For one thing, children's bodies are not as rigid and frail as adults' bodies. They have more of an "elastic" nature to them. They can stretch and twist in ways that would mean serious tears and injuries for adults.
On top of that, young bodies are always growing. Bodily resources and energy are constantly being used to create bone and muscle tissue. Organs are growing and developing. Since the body is always engaged in this process anyway, healing also happens faster. Tissue can be repaired and reconstructed more effectively than it can in adults, who have not been truly growing in years or decades.
Finally, many children are in better physical shape than adults. With this physical fitness comes more efficient cardiovascular systems. As blood moves easily to areas on the body that were hurt, healing happens quickly. Adults who are no longer in as good of shape may not see the same benefits; healing still happens, but the body takes longer to mend broken parts.
Of course, this does not mean your child will not endure significant pain and suffering, that he or she will recover quickly from any injury or that you will not see some significant medical bills along the way. When your child gets injured, make sure you know about all of your legal options.
