A new report released by the World Health Organisation recommends all children under two should have no screen time at all.
The report makes recommendations around activity levels, sleep and screen time.
For children between the ages of two and four it says to limit screen time to just one hour a day and less is better.
Concerns over screen time come from children being less active which is related to weight gain and illness later in life.
The report specifically talks about sedentary screen time which is where kids are simply plonked in front of the television or screen.
Some experts say that is too simplistic a view of what's going on.
Teacher and mum Paula Morton says, "He [her son] doesn't just sit there and zone out, there's obviously things going on in his brain at the same time so in that sense it's quite useful. I don't know how we'd make dinner and cook and clean if he didn't have something to watch."
Jenny Griggs is also a mum and a nurse and says it's up to the parent to decide.
"I think it's up to you as a parent to decide for your kids what they need and what is best for them."
