Aww congrats sa turning 6! Honestly, marami sa circle ko ang nag-transition sa S26 Two around that age, pero kasi bawat baby talaga ang iba so mas better mag-check muna with your pedia kung okay na talaga for your lo since every kid has different nutritional needs pa. You can use up that One pack muna while you consult, then transition na if doc gives the go-ahead, that way walang sayang at sigurado ka na okay para sa baby mo!
