When I saw my two-years old son rubbing his eyes while playing video games online yesterday, I suddenly found that children couldn't completely understand what phones or pads are to them, are they a toy or maybe friends that can comfort them? All the things online seem very attractive for children. They can break the relationship between children and their parents which can have a bad influence on children's academic results or future career. These children who spent too much time online usually become autistic and hardly believe others. On the contrary, children who live along with love and company from their parents usually keep far away from the Internet which won't attract them anymore. They are easy to success in their future. So, the key to protecting children from being hurt online is what their parents want to do for them.
