Help! Distressed mother!

Mya • Yummy mummy to Liyana 💕

My three month daughter has eczema and had a really red sore neck! She was crying all the time and the doctor prescribed her a mild gel for her body and face and a mild steroid cream to be applied on the red sore areas twice a day. It’s been two days since using the cream and her neck is now white and discolored! I’m so upset that she is now scarred for life! Please help
