Normal ke susu ebm blh rasa mcm santan?

Eh, that's actually normal lah! A few of us tried and noticed the same thing, when EBM thaws, sometimes the fat separates and it can taste a bit like santan, especially if you expressed in the morning or after longer gaps. Completely fine to give to baby, don't worry, that's just the natural fat content doing its thing, nothing spoilt or wrong. Just make sure you gently swirl the bottle to mix it back together before feeding, jangan shake because that can break down some of the good stuff in the milk.
