Can you delete the Skype app from your PC? Just delete it. You can install it again at a later date if you want. Also, my kids eat crackers sometimes for dinner and they live.
I keep a stock of hummus, crackers, nuts, cheese and veggies and whip up a "platter" of healthy munchies when I don't have time to feed them a proper dinner. They actually love it and request it a lot.
I also hear you about leaving the kids alone. It is hard. Can you find a yoga class early on a saturday morning? Or maybe during your lunch break? Also, I have come to realize that my kids actually love it when I go out and they are home alone- they prefer it to me being there, LOL.
