At what age do you think is appropriate for youngsters to have their own (adult) personal computer, laptop, tablet (considering Parental Control)?
My daughter got her first (adult) tablet when she turned 3 and then the first PC desktop when she was 6. All with parental control. She has limited screen time during the years. I noticed creativity, skills in using different applications and researches, projects, etc developed exponential during years.
Now she has a MacPro laptop that she loves and she is self-teaching coding.
