I removed the internet access from the tablet and have been keeping my phone out of reach as much as possible. for the most part I am fine with him surfing netflix and youtube he has only come across one or two posts that made me go "WTH is that??" ....and to be fair I mostly removed access because the tablet was getting sluggish and I did a total reset to get rid of junky apps too.
Out of nowhere .. my kid is suddenly saying DOUFUS .. like wth ?? where did that come from.. He thought it was hilarious and was grinning like a nut. Wherever he saw, or heard it must have been on youtube or netflix. I couldn't help but hide a grin.. it was rather amusing. However I would rather he didn't go around shouting it out ... at least I hope he doesn't do it in public LOL... because I really would have a hard time not laughing.
I decided to keep the tablet without access and I have been ripping his DVD's to smartphone format and loading them up on a big SD card so he has plenty of his favorite shows to watch without the internet. Seems like you can't uninstall the damned youtube apps, removing them from the desktops is worthless because he just goes straight to the installed apps in settings and opens it from there LOL.
He seems happy enough without it and I'll get through his DVD collection sooner or later and just keep cycling through them and switching them out every week or two.
