Hi mama! At 14 months, technically pwede na siya ng Yakult pero I'd personally check with the pedia muna about how much at how often, kasi may added sugar pa rin siya and some babies can get tummy issues if they're not used to probiotics yet. A few of us moms give it as an occasional treat rather than regular, pero better safe than sorry talaga, lalo na first-time mom ka pa!
