Aw first-time mom worries talaga yan, I feel you! Rashes sa baby's face can be from dry skin, heat, or sometimes just sensitive skin pa lang lagi, pero since baby's skin is super delicate, best talaga to have the pedia check it out para sure, they can tell you exactly what it is and what's safe to use. In the meantime, try keeping her face clean and dry, and ask the doctor if okay lang mag-apply ng plain moisturizer or if kailangan ng something specific. One of my mum friends' baby had similar rashes at the pedia recommended a gentle cream lang, so don't worry too much, usually madaling ma-address once you know what it is!
