Congrats, mama! 2 days of EBF is such a huge win, lalo na after what happened with your first baby, kaya mo yan! A few of my mum friends who mixed fed their first eventually went EBF with their second, and they said the worry about supply never fully goes away, pero the fact na you can already do it even for 2 days means your body can produce enough. Since you're still in those early days and the dehydration worry is real for you, maybe check in with your lactation consultant or OB soon just to make sure baby's latch is deep and you're draining well, that's actually the key to building supply, hindi lang about stress and pumping. You've got this, at kaya mong i-reach ang goal mo!
