<p>We have a program by which we can block or limit computer access on all the computers on our network. When our D was a senior, she actually asked us to block the internet for certain periods of time; Facebook, YouTube, etc. were too distracting from homework and college apps.</p>
<p>The main control is on my computer, and I control all the other computers. If my D needed access to the internet for something, she’d simply ask, and I could give it.</p>
<p>It worked for us.</p>
<p>PS This program is called SafeEyes, but there are others like it. But note: your computers have to be networked to be able to operate it from your computer. (You could put it on a computer and have an administrator’s password there.)</p>
