Blues with playtime

on the age of the child,” Dr Greenfield said.

He said in many households, screen time was an expectation rather than a reward for chores done or other goals achieved.

Most importantly, it was important to lay down boundaries when it came to device usage. When and how much screen time depended on the household.

“At the end of the day, the parents have to be in control,” Dr Greenfield said. “You’re the parent, you are the one paying for the data or device.

“You have ultimate say, regardless of the age of the child.”

Children also needed to know there were consequences for breaking the rules.

Punishment might include stopping or limiting data, disabling the wireless functionality on the device or restricting the use of apps.

“The technology (for punishment) can be quite clever, but it’s not about all or nothing,” Dr Greenfield said.

“To me the main things are those limits, and you have clear rules so you don’t have an argument every single time.

“It’s also about being clear on what happens when a child breaks those rules.”

The psychologist said parents could discuss rules with older children, but ultimately it was up to the adult to set and enforce the boundaries.

Mr Longley also advocated balancing screen time with play.

“The number one thing is balance,” Mr Longley said.

“The amount of time the kids spend on screens needs to be balanced with being outside and being active.

“It’s not about abstinence.”
