Hi Ms Kang, as a first time mummy without proper knowledge in handling and storing breastmilk, I will really wish and appreciate that you can address my following questions: I dont latch my baby so do we also require to feed on demand for bottle feed baby? I usually pump every 3 hourly however at certain time of the day (i.e. attend to baby etc), my pumping interval will drag to 4-5hr. Will it affect my milk supply? For milk taken out from the fridge, I use traditional way of warming it (i.e. pour hot water in a bowl and soak the milk bottle). Will this destroy the nutrient of the breast milk? After warming, how long the breastmilk need to be consumed? How long can breastmilk be left in a room temperature & air conditioner room respectively? If baby has consumed the breastmilk from bottle and cant finish, how long does the remaining milk need to be consumed? How long do we need to consume the breastmilk if i put in insulated bottle (i.e. pacific baby 3-in-1 bottle)? Description indicate that the bottle can keep the milk warm up to 6hrs. I was told we should pump 10-15min for each breast. Can we exceed more than the advisable timing?
