I don't know what would work for you, but in my own experience, it goes away by itself in a couple of months. We had a similar problem, although not severe. I restricted my use of milks, tried changing my diet, put the baby on soy milk, and tried changing his baby wash as well as laundry detergent. The baby wash and laundry detergent change made the most difference (even though the acne was really only on his face). If nothing else works, just be secure in the knowledge that it will go away in time. Good luck.
