I understand how parents could feel a bit overwhelmed (to say the least!) about what activities to do for, or with their children, for long periods at a time, specially during holidays!
On the other hand, I can tell you of the many benefits of not having kids glued to the TV/screen while they are not at school.
In terms of scientific research, a good place to start is to know, and to be re-assured that, our efforts in limiting content and the amount of time children spend on the computer or in front of the TV, can indeed make a positive difference in our children’s lives.
