Note: Lei Ting, a mother in Beijing, gave birth to a son in 2011. The 31-year-old woman, who works for a big technology company, never posted her son's pictures on the Internet, hoping to provide a safer and quiet environment for the child.

I am proud to be a mom and I am also learning how to be a sensible mother.

It is common to hear and see some children in danger through parents' carelessness or injured by those with bad intentions online, which is why I'm always concerned.
