What milk tastes like Nan Optipro Three?

Ay alam ko yan, picky eaters talaga with milk taste! A few of us moms tried switching from Nan kasi mahal na, and honestly walang exact match, pero maraming kaibigan ko na successful sa Lactum or even Bearbrand, kaya siguro pwede mong subukan ng gradual na mix-mix lang with his current Nan para hindi ganitong shock sa lasa. What worked for one of my mum friends ay yung strategy na 70% old milk, 30% new milk, tapos slowly adjust the ratio over a couple weeks, mas nakakahang anak kaysa biglaan talaga!
