If he does accept it, then after a week or so, try doing a bottle mix of ½
breast milk,
and ½ formulas. If you wish, you can gradually go to a bottle mix of ¼
breast milk and ¾ formulas, then totally to all formula depending on how he accepts it. This way you will use up the breast milk and he will get used to the formula taste. Once you are on formula and he is accepting it, do not reintroduce breast milk bottles. Try mixing the infant rice cereal with breast milk.
