I don't have any personal experience with cream of rice, but wanted to say if you were hesitant to try it I would highly recommend the Happy Baby - Happy Bellies baby food. They have oatmeal, rice and multi-grain. It's organic and I've found it at Target

Nowadays I'll sometimes mix some with Allie's veggies and she
loves it, especially asparagus and cereal
ETA: As far as the cream of rice, I think baby cereal tends to be broken down more so that it doesn't upset a baby that is new to solids tummy. It's also fortified with vitamins and whatnot. Other than that, I don't know of what other differences there may be
ETA AGAIN

: You know what. After thinking about it for more than half a second, I would probably just buy what you found. It seems like it's natural and doesn't contain anything scary like you saw in that other package.
