Baby Eating Tip
My baby is perfectly healthy and eats cheese, shellfish, wheat products and even non-pasturised milk and apple cider. What we are doing is totally sterilizing food to make it "phood". Humans have always been exposed to microbes as it is what makes our immune system strong.
Check out the Weston A. Price foundation. Although I do not adhere to all it's dietary recommendations - I do think it is on to something.
Also, limit or eliminate all processed foods. They are not good for you. Learn to cook from scratch with basic ingredients.
