Hi there mummies. I'm wondering if a baby can be allergic to breastmilk?

No, i don't think so. Breast milk are the best for the babies. However, if they do develop any rashes or allergies, monitor them 1st. Usually, it could b due to mummy's diet rather than the breast milk itself. It's important to continue breastfeeding babies as it is believed to be the most nutritious milk for them.
