Neck rashes (Part 2)

Hello mga Mommies. Thank you po for all your inputs and suggestions on my previous question. I went to pedia and was advised to use Drapolene Cream. Here's the result po. Is this alarming po? After almost a month, from pinkish na may umbok to flat white patches but nagspread out 😢 please help me with your inputs po, i'm kind of paranoid na. Should i consult with derma na po? Thank you very much PS. I'm a FTM and my baby is turning 2 months old po
