Frequency of use by age (in year;month) among children reported to have used touch screens in the past.
Data is grouped in deciles to even the number of infants in each category. As in Fig 1, “<1×” stands for “less than once a”; “wk” stands for “week” and “mth” for “month”.

Activity reportedly liked by age decile.
Caregivers’ report of whether their child enjoyed an activity (red) or not (white), grouping children in ten equally-sized age groups. The limits of some of the age groups (in year;month) are given in the x-axis (see Fig 2 for full list).

Gestures displayed during interaction with a touch screen by age decile.
Caregivers’ report of whether their child displayed an interactive gesture (red) or not (white), grouping children in ten equally-sized age groups. The limits of some of the age groups (in year;month) are given in the x-axis (see Fig 2 for full list).
