I started giving y daughter oatmeal cereal 2 weeks ago. I thought you were just supposed to start with single grain cereal, I idnt know you were supposed to stat with rice cereal. I think my daughter has been more fussy throughout the day since we started cereal. Do you think its from the oatmeal cereal? Is it ok to switch to rice right now? By the way Ive only given her 2 tablespoons of formula with 2 teaspoons of cereal with her bottle for her night feeding.
