Aww, I feel you sa gastos, lalo na with twins! Honestly, I'd ask your pedia first bago mag-switch kasi lactose intolerance can vary from baby to baby, at gusto natin sure na ang Nestogen Low Lactose talaga ang best fit para sa kanila, some of my mom friends tried switching formulas without checking first at medyo complicated ang adjustment. The pedia can tell you kung ready na sila for low lactose versus lactose-free, kasi basta ang goal is hindi sila ma-upset stomach or mag-suffer, diba? Keep me posted kung ano-approve ng doc, marami kaming sa group na may lactose-intolerant babies so pwede ka rin mag-share ng experience later!
