Ay naku, I feel your worry talaga, it's so heartbreaking seeing your baby scratch all night long. The pedia is right na kailangan simultaneous treatment ng buong household, kaya good call na kayo ay nag-start na; for your husband though, I'd really suggest he see a dermatologist din if possible kasi may specific treatments for adults na iba from kids, at important na ma-prescribe correctly para mabilis maubos. A few of my mum friends had the same situation and nag-wait sila sa insurance or nag-apply sa charity clinics (marami sa government hospitals) para sa mas mababang bayad, worth checking if available sa area ninyo. In the meantime, make sure lahat ng bedding, towels, at damit ay ma-wash regularly sa mainit na tubig and dried in the sun dahil tumutulong din yan, plus keep your LO's nails short para hindi malalim ang scratches. Rooting for your family na mabilis makabawi, kaya ninyo ito!
