Dr Holloway's research looks at how kids are using tech and she has some helpful tips for parents using technology with their children.
She says it's important children are active in their use of technology and that parents or older siblings 'co-use' tablets or similar technology with young children.
The research is the first of its kind to actually go into family homes and find out how children and their parents are using games and apps and she says there's no signs of excessive use of technology among young children.
