It is like he is going through a heroin withdrawal! Bouts of sobbing begging for it back. We bought him and DS (6) iPod touches for Christmas and were naive at the time-suckage and addictive nature of the things. After a lot of wrestling with my conscience, I finally snapped and took them away.
My younger one was not really bothered but my older one had really been changing, much less inquisitive and imaginative. Seemed to live for the bloody video games.
I feel bad that I let them have a taste, but I can´t believe how evil the things are! Want my boy back...which is already happening after 4 days off the thing, thank goodness.
