Hi mama! I haven't personally tried Mycoco cream, pero honestly with atopic dermatitis sa 5-month-old baby, mas safe kung i-check mo muna with the pedia kung OK lang siya before trying anything new, kasi sometimes what works for one baby's skin can trigger flare-ups sa iba. A few of us mums sa circle namin have babies with atopic dermatitis din, at ang common advice talaga is na konsultahan muna ang doctor about which creams are safe at proven effective para sa age ng baby, kasi steroids vs alternatives is really something na kailangan i-assess ng doctor based sa severity. Hope your baby feels better soon, mommy!
