Hay, I feel you, one of my mum friends' baby had the same issue and it took a while talaga bago mag-improve kahit may prescribed soap na. Since your pedia already recommended Cetaphil AD Derma, I'd really suggest going back to them or asking for a dermatologist referral kasi sometimes keratosis pilaris needs specific treatment like lactic acid or urea-based products, hindi lang gentle soap, mas safe para sa baby na may professional guidance. The good news is marami nang pedia dermatologists offering online consultations now, try searching sa Facebook or asking your pedia kung may recommendations sila, bec consistency and the right product combo talaga ang key dito!
