COCO Maslin loves colouring books. The four-year-old loves to grab her pencils and is meticulous about staying within the lines.
She also, perhaps equally, loves colouring in pictures on her iPad. Using an extensive palette of colours from a bar at the bottom of the touchscreen, Coco carefully selects her choice of colour then uses the tip of her index finger to colour in a butterfly.
Coco, a participant in Swinburne University's BabyLab study on children's iPad use, loves her iPad. ''It's great for car trips and those times when they would normally be stuck looking out the window,'' says Coco's mother, Melanie.
Melanie Maslin has a one-hour-a-day screen-time rule for her daughters, Coco and Roxy. Combined, they get to spend about an hour using devices such as mobiles, iPads, television and computers a day. ''I think one hour is enough,'' says Ms Maslin. ''On Sundays when we are really active, they won't use any screen time at all. There is so much you can do with a child that's one-on-one and interactive.''
Having said that, Ms Maslin says she has carefully selected apps on the iPad she thinks will help aid her daughters' learning - with the exception of a few games for entertainment.
It is one of these games that Coco lists as her favourite to play on the iPad. ''My favourite is Mega Run,'' she says.
