Eh, honestly tak banyak orang dekat circle aku yang try Mamex step 1 specifically, kebanyakan guna Mamex Cherish or switch ke brand lain after a few months. From what I know Mamex Cherish supposed to be more premium with added nutrients, tapi honestly both are Dumex products jadi quality should be similar lah. Best way is try dulu small tin to see if your baby's tummy okay with it, sebab setiap baby berbeza kan their tolerance!
