My dd also hated rice cereal. I just stopped offering it to her for 2-3 days, then started again with the baby biscuits (I don't know if they're called that) included. And since one week she really likes them. Sometimes she finishes, sometimes she is almost finished. Just once this week she didn't feel like eating it, so I didn't force her.
I also put half an egg yolk (boiled for almost 10 minutes) and homemade cottage cheese.
I also should say that my dd doesn't like it when it's too runny/liquidy. So I suggest you can start experimenting after a 2-3 day break (if you want her to have the rice cereal of course). Me, I'm kind of confused with the other cereals so I just go with the rice (minimum risk of allergy).
