Hi K.,
If she doesn't like cereal, she doesn't need cereal. There's no nutritional need for it.
I specifically wanted to respond to your post, though, because I respectfully disagree with some of the suggestions below. I do NOT think it's good, and it may not be entirely safe, to flavor an infant's cereal with processed, sugar-filled foods like the Gerber stuff. These foods contain additives that can produce an allergic reaction in some babies, and even if that doesn't happen, the best-case scenario is that they'll teach her to expect refined sugar with everything she eats.
What I recommend instead is stepping back, waiting a few weeks, and then trying other baby-friendly foods like mashed banana, mashed avocado, mashed/pureed peas, etc. Please try single-servings first, though, not combos. And if she doesn't like something, wait a day and try something else. My own son HATED rice cereal, banana, and avocado, but he was thrilled with peas -- and still is.
Best wishes,
Mira
