Mama, please schedule a pediatric check-up as soon as possible, your baby should see a doctor within the first week or two, and the pedia can advise you properly on what vitamins or supplements baby needs right now. Hindi dapat mag-decide based on advice lang without the doctor's assessment, especially pang-newborn pa lang. Your MIL means well, but every baby is different, ang pedia ang makakasabi if there's a need at anong safe for your little one.
