Oo yan, ganyan talaga minsan ang mga babies, picky eaters na from day one! A few of us tried rotating between brands every few weeks para hindi gaano ma-boredom, pero honestly it's hit or miss kasi every baby's tummy is different. Have you checked with your pedia kung okay lang ang frequent switching, or kung may underlying issue like lactose sensitivity na nagpapasawa sa baby? Sometimes it helps din mag-try ng different feeding bottles or temperature ng milk, pero mostly patience lang talaga while you find the right formula na mag-stick sa baby ninyo.
