Is it possible? At around 4 mos., I started Kylie on rice cereal but it made her extremely irritable(just like her sister did) so I switched to oatmeal with no problems. Yesterday I gave her Mac. & Cheese Dinner by Del Monte Stage 3 but I mashed it up some more. Her face broke out terribly around her mouth within the hour but no gastro issues or irritability just Big red whelps or hives on both cheeks, sides of mouth and chin. It has rice flour in it. The onions and spice(that's all it says) in it she has not had before. Any educated guesses? Could the rice cereal cause gastro problems and the rice flour cause the hives only this time? Thanks for any advice!
