Hay, mama, this is really important, so please talk to your baby's doctor or the NICU team right away if you haven't na, kasi they can guide you best on what your preemie needs and how to express safely for his age. A few of us moms with preemies, ang experience namin ay ang medical team talaga ang best source, they'll help you with expressing, storage, lahat ng kailangan. You're doing great by thinking ahead!
