Aww, first-time mom ka pa lang, understandable ang concern! Since your baby's not taking well sa Ceelin, I'd really suggest bringing it up with your pedia dahil they know your baby's specific needs best, may iba't ibang vitamin brands out there pero important na appropriate for baby's age at hindi mag-cause ng tummy issues. A few of us moms tried switching brands or even asking if liquid vitamins work better than the orange ones, pero talaga, your doctor can recommend kung ano best suited sa baby mo, especially kung may specific deficiency kang concerned about.
