We're getting ready to start solids with LO, and I'm kind of confused about baby/infant cereals, like this:

http://www.amazon.com/Sprout-Whole-Grain-Cereal-Oatmeal/dp/B00BN1U4SS/ref=sr_1_3?ie=UTF8&qid=1376259916&sr=8-3&keywords=whole+grain+baby+cereal

Is there something special about baby cereals versus just regular cereals like oatmeal, quinoa, etc?

If you fed regular grains instead of these ones specifically marketed for babies, how did you prepare them?
