Hi, mommy! Mahirap sabihin based sa description lang, so please bring her to a doctor or clinic para malaman kung ano talaga at ma-address agad, better safe than sorry, lalo na if she's scratching a lot kasi baka makagawa ng wound. A few of us mums have dealt with rashes and skin stuff sa babies, at lagi naming dini-check ng doctor agad para sigurado. Let me know what the doc says, okay? Rooting for your baby!
