Nana and pepper:: for the first 6 wks, actually no need to pump after latching, just solely latching will help build and stabilise your milk ss. However there are some mummies i know who still pump after latching to FULLY empty the breast, so as to tell the breast MAKE MORE MILK, if you leave milk inside, the body will adjust to bb's demand that he only needs this amt, thus i will just make this amt.
For the pumped milk, you can store it in the freezer. After 6 wks, if you would like, you can thaw the frozen milk and then introduce the bottle. And from then on, if you would like to pump instead of latch, instead of freezing, you can also store for 48hrs in the lower compartment of the fridge... but milk thawed once CANNOT BE FROZEN and RETHAWED. same for the milk that is kept for 48hrs and heated. I hope you understand what i mean.
So if you wish to store frozen milk, whether in bags or bottles, u need to count properly not to waste milk.
