May I know when is the best time to start breast pump and feed using a bottle?

You can start pumping by first week after birth or as soon as your milk production is a lot. It depends on individual. For me, I only start pumping a week after I direct latch both of my kids and after I did my PP Massage. Reason being is to ask my makcik urut to help ease my engorged boobs, help to clear my milk duct, better stimulate milk production. And as for bottle feed, I will give anytime when they feel hungry, if they dont feel full even with BM/EBM. I will give once or twice a day. Then, as soon as I am going to work or baby's in IFC I will FM atleast 80% and at night will be BM/EBM.
