My son is 17 months old now and my pediatrician told me that it was ok to start my son on cereal at 4 months old and for two weeks if he was taking well to it to try oatmeal for a week and if he did well with that the following week to try barley and then from there he told me it was start him on the fruits and veggies. You want to try veggies first though because if you do the fruit before the veggies they will not want the veggies they will want the fruit because it is sweeter. It really depends on how you feel its your child if you feel that she is not getting enough then go with your instint and start her with the ceral.
