A study has revealed that three out of four children under-five now has access to a tablet, smartphone or computer.
Market researcher Childwise has said three-quarters of the children have access to a connected device and most of the three- and four-year-olds had their own tablet or PC.
The BBC's Cbeebies was the children's favourite channel and YouTube the most popular app.
The study showed that children were typically spending an average of two hours and 48 minutes a day watching video content.
Voice-recognition gadgets such as Apple's Siri and Amazon's Alexa were also increasingly popular with the preschool age group.
The survey was carried out with 1000 parents contributing.
