I just finally stopped completly, but it took me about a month, first you need to make sure he takes the bottle well, and what you shoul ddo is
pump and give him
the breast millk in
the bottle also alternate breastmilk and formul aso he starts getting use to the formula flavor, one he is ready for the bottle and formula then the pumping should start weaning off, I startd pumping every 3 hours for couple days bc he was eating every 3 then then every 5 and then every 8 then once a day, then ever
