Aw, poor baby! Yan talaga nangyari sa amin with my youngest after nag-try kami ng new product, sometimes ang skin ng kids is just super sensitive sa certain oils, kaya it's good na you're planning to see the pedia soon kasi they can properly check if it's a reaction sa oil or something else like eczema, and they'll know kung anong safe to use sa age nya. In the meantime, I'd avoid any oils or heavy creams muna and stick to plain water for baths, pero definitely bring her to the doctor para ma-rule out kung may infection na from the scratching. Alam mo naman ang kids, once kati-kati ay talagang kaka-scratch lang ng kaka-scratch so best to get professional advice na para ma-treat properly!
