The introduction of complementary foods First offer  a variety of single-ingredient foods (such as pureed vegetables, fruits, grains and meats),  in any order that parents desire Iron-fortified cereal is often a good choice as iron stores from mother become depleted by about 4-6 months of age.  Recommend only providing 1-2 new foods per day in case the child has an adverse reaction  The main calorie source for these infants should still be formula or human milkor Important foods to avoid include: honey (due to the risk of botu...
