Hindi ko ma-recommend na ibigay agad, mama, better to check with your pediatrician muna kung pwede na ba for your one year old since it's formulated for older kids. A few of us nag-try na mag-jump sa next stage milk thinking same lang, pero turned out ang tummies ng babies namin were a bit upset kaya nag-go back kami sa age-appropriate ones. The formulation talaga is different depending sa age, so mas safe kung tanugin mo muna ang doc before introducing it. Pwede mo naman i-save para sa next year kung sakto na sa 3+ requirement, problema lang yun haha!
