I also did this when I was pregnant...I was a total flake! That's all I did was risk our house being burned down.
I exploded boiled eggs and even burnt already cooked chicken wings and my poor kids couldn't eat the pizza...on more than one occasion...how do you burn pizza? LOL LOL
Since then I bought one of those timers that goes off and gives me a near-heart attack everytime...but at least I know when the food is done!
