he's probably used to the formula and if you haven't been breast feeding from the begining, you won't have enough of a supply to feed him with only breast milk right away. it kinda works like a supply and demand. the more you breast feed the more milk you will produce. for now, I would offer him the breast first and then finsh him off with the bottle. after a while, he will get used to it and you will build up the supply for his little demand. if you have problems with it, call your doctor or the local hospital and get the number of a lactation expert. they have them in my area and they are SO much help. good luck to you
