Uy, importante talaga yan! Para sa safety ng baby, kailangan mo munang i-check ang label ng Lactum mo mismo, kasi different brands may different guidelines, and storage matters too (room temp vs. ref). A few of us mums usually follow kung ano ang sabi ng manufacturer sa packaging, pero honestly, pag may doubt ka, better safe than sorry with baby's milk. Kung may specific instructions sa Lactum box mo, yan ang susundin ko, or you can call their customer service para maging sure, mas peace of mind ka lang talaga!
