Aww, ganyan din nangyari sa anak ng kaibigan ko around that age, sometimes it's just a phase or baka overwhelmed sila sa lasa/texture, lalo na kung nag-transition na kayo sa regular milk from formula! Could also be na may minor tummy sensitivity or even just picky phase talaga, pero mas safe na i-check mo with your pedia kasi may times na may underlying reason like lactose intolerance or something. In the meantime, try other dairy sources like yogurt, cheese, or ice cream kung willing niya, pero definitely ask your doctor para sure!
