Cereal=poison?

My goal is to try to make as much as I can from scratch.  As I come to a need in our home I go on-line to find a recipe for what I need.  The latest item is cereal, my kids LOVE cereal!  I am guilty for feeding my children cereal for dinner on the nights I just don't wanna make anything. It's quick easy and so handy. I never realized I am feeding my children, my family, my walking hearts, poison!  Even those lovely finger cereals we give our babies are poison.

So I tell my kids "NO MORE CEREAL IN THIS HOUSE!" so my oldest sons reply was "I would rather starve than eat oatmeal!"- Great so instead of poisoning my children, I will just starve them.  What is a mom to do?  I have done hours and hours of research and I have found the recipe.  I promise once I make it and of course have my little lab rats, I mean children test taste I will let my friends know.  But in the mean time get rid of the poison in your homes and make oatmeal, eggs, pancakes, waffles, anything but cereal!
Don't believe me I double dog dare you to find a recipe for a cereal you can buy in the store!  Good-luck
Here is the website where I found the recipe I will soon make.
