Now, about half of American children have cellphones(手机). And that has many problems, like questions about etiquette and the phone fees(费用)—about ＄5 a month.
“The best thing parents can do is to educate, educate and educate,” Dr Milteer said, “They also need to make rules. One way is putting a basket out where children put their phones in at home. Then they can’t go into their rooms and call their friends,” she said, “If they need to use, they can use the house’s phone.”
Parents also complain to her about their children texting under their quilts at night. “Don’t worry,” Dr Milteer said, “Let them know there are rules. There comes a time when parents have to be parents.”
We hear that driving and texting are dangerous, but Dr Milteer said that it is dangerous for children to text when they are walking in the streets.
