If I pump out my bm on the 1st and kept it in the mini fridge, can I still feed my LO? It's already 4 days

Mini fridge would means milk that is not frozen nd refrigerate only. Ideally is to clear it within 3 days but it has last maximum till 7 days. Haven't tried for so long though. Nonetheless, please chk and smell Yr BM before giving it to Yr baby. If the smell is weird, pls discard it straight away.
