Dear Happy mama,
I can only share with you my case, I think there are more official information for the answer.
Anyway:
點樣儲存已經泵咗出嚟嘅人奶?
In the bottle or storage milk bag, and milk cup, and put it in refrigerator
泵咗出嚟嘅人奶可以儲存幾耐?
Upper level (freezer) for 3 months, lower level (refrigerator) 1-2 days.
會用咩方法整熱番d奶?
Warm water, around 40C and warm it up untill 40C
Hope this help!
