我昨天带孩子看医生，医生是这么说的。

医生说我孩子是Seborrheic Dermatitis (溢脂性皮炎）。症状如下：it starts at 3 weeks of age, usually starts as acne. Then it becomes burned and inflamed and bumpy. Soon it becomes yellow crusty. Then it becomes very oily and forms tiny crust. At the last stage it may become slur blotchy.
医生的医嘱是：use clear water to wash face twice daily and pat dry,then apply sparingly 10% hydrocortison OINTMENT twice daily for 2 weeks. After 2 weeks, switch to Aquaphor healing ointment, apply twice daily. Shampoo baby\'s hair daily with Johnson baby shampoo.
医生特别提醒要用ointment, not cream.
去看医生前我已经给孩子用了5天cetaphil.现在我用hydrocortison擦孩子的耳朵部位，用Aquaphor擦脸和脖子。效果还不错。
