Any particular reason you are pushing hot cereals? She just may not like the texture, maybe hear digestive system doesn't do well with them. Lots of times, kids with food allergies or sensitivities don't like the things they are allergic or sensitive to. And being fairly refined foods, they don't have a whole lot going for them nutritionally.
At a year old, my son loved eating plain, whole organic yogurt with a mashed banana in it for breakfast. The banana seems to take away the bitterness of the yogurt. Sometimes I would mix in a little oatmeal, but the yogurt was always primary.
