Most infants do not need to start on solids until they are at least 6 months of age. If for some reason your daughter seems hungry after bottle or breast, whichever you use, you may to start her out on something other than cereal. My son's first foods were mango, avacodo, and sweet potatoes. He did not start eating solids until 5 1/2 months, though we also tried at 4 months. Mango is a very mild fruit, and easily digestable in infants. I was advised that it is not a good idea to mix an infants foods, and that ALL fruit should be cooked. I would either give her the fruit, or the cereal, not both. it is very possible though that she is just not ready for solids, and you may need to take a step back. It is also a possibility that she just doesn't like the cereal. (Have you ever tried it? It is not good.) I would experiment with other mild foods, and if she still doesn't want them, I would just wait a month or two. I hope that this helps.
