We skipped rice cereal and started with avocado, sweet potato, etc. But when we did do cereal, we just did regular organic oatmeal (not instant) from Trader Joe's and mixed it with either a ripe banana or organic applesauce.
We skipped rice and started with oatmeal cereal just after 6 months. I've used both Earth's Best and Gerber organic varieties and like both. The Earth's Best seems "fluffier" and Gerber seems smoother, but both are good to us.
We use Earth's Best Organic rice cereal. You can get it just about anywhere (walmart, target, grocery stores). We give it to DD at breakfast mixed with fruit and she loves it that way.
