Aww, inverted nipples is tough, mama! At 2 weeks old, your baby should be taking around 30-60ml per feeding, roughly 8-12 times a day depending sa gusto niya, pero honestly, every baby is different kaya observe mo lang kung satisfied siya at wet diapers niya are good. A few of us had the same issue and pumping is totally fine; ang important lang is consistency and making sure you're draining well para hindi ma-clog ang ducts mo. Keep monitoring kung lumalaki siya and wag mag-stress, marami pang time to figure out kung gusto niya ng direct latch or exclusive pumping lang.
