I was appreciating my family photos on my computer, admiring my two beautiful babies, when I found a disturbing trend: my laptop was in almost all the pictures. There was my daughter, 8 months old, playing at my feet while I was typing away on the couch. There was me and my son, with the laptop at my side as I held him in my arms.

I’d heard about the Internet addiction before, but always assumed I was something limited to socially challenged guys who played too much World of Warcraft (a computer game). Now it seemed my Internet “habit” is slowly but surely crossing the line. Sometimes I find myself up at midnight, surfing the Web while my family are sleeping. I read news, keep up with friends and write my blog … just for something to do.

It turns out that I’m not the only mama who is addicted to the computer. These moms are contributing to a growing global addiction. There’s a movement among psychiatrists (doctors who specialize in mental diseases) to recognize the Internet addiction as an official mental disorder. And a recent Stanford University national survey found that 14 percent of Internet users find it hard to stay away from it for several days at a time; 9 percent try to hide their “unnecessary Internet use” from their loved ones; 8 percent admit they use the Web as a way to escape problems.

You’re likely not the kind of addict who doesn’t bathe and abuses drugs to help her stay “up” for more online time. You may have noticed, though, that going online has become a necessary part of your life, which, at least, means a load of clothes go unwashed.

It may also mean you’re missing much time with you baby – something you probably do care about.
