What Is a Breast Milk Thermal Bag and Why Do You Need One?
Jawaban Langsung
A breast milk thermal bag is a portable insulated container designed to maintain the cold temperature of expressed milk until you can refrigerate or freeze it. Unlike a refrigerator, it doesn’t generate cold; instead it acts like a pause button, slowing down warming and preventing bacterial growth. Pairing it with frozen ice packs allows you to keep milk cold for up to 24 jam. Keeping milk cold isn’t just about taste – it preserves antibodies, enzymes and vitamins that are vital for your baby’s immunity and growth.
