There is a British report by Ofcom. It says that children are using electronic devices (电子设备) more and more often.

Nineteen per cent of children who are 3 to 4 years old have a tablet and use it for more than an hour a day. Children who are 12 to 15 years old spend over 20 hours a week online, and 70% of them use their phones in bed.

A psychologist (心理学家) said that parents need to have rules as to when and where their children use the devices. A mother said that it causes a lot of arguments to get off the electronics, and the arguing usually turns into the kids’ continuing to use them for a long time.

There is no ideal limit to using electronics, but the advice is to limit it.
