Ay anak, that's actually a question you really need to ask your baby's doctor habang nandoon na siya sa hospital, kasi ang dilaw na iyon ay may different reasons depending on age at iba pang factors, at sila ang makakasiguro talaga based sa labs at check-up nila. I know it's scary, pero good thing nandoon na kayo at normal ang labs, that's reassuring! Your pediatrician sa hospital will have the best answer for your baby's specific situation, kaya don't hesitate to ask them directly, okay? Sending you both so much love.
