Its a timely post to open our minds to where our children are heading. Personally i used to let my kid play / watch things online with my tablet so that it allowed me to do my work. But recently i stopped it after seeing results of few studies, showing that it can depress the congnitive development of kids.
After all its our children we have to give some time for them.
Also for adults consuming more media at one time or multitasking is found to reduce their ability to concentrate.
