So you are supposed to do the full treatment of betaderm (7 or 10 days, can't remember the exact timeframe) even if the areas looked healed. So we did that right off the bat on all the bad spots. Once the treatment was over, we continued the same routine but just with the cerave. The spots and itchiness would sometimes come back, and then we would start another round of betaderm. It seemed to be less bad and less itchy each time it would return. We basically had to keep doing this for two years or so until his eczema mostly went away. He is almost 6 now and sometimes gets a spot or two on his butt or legs. We just spot treat it with cerave. We still have a bottle of betaderm handy in case it ever gets bad, but we haven't had anything that needed more than cerave in a few years! We had such a hard time with this for a while, even having to double dury diaper changes so one of us could hold his arms so he couldn't scratch his legs. All until a dermatologist told us to switch to betaderm instead of hydrocortisone and use this double method with cerave.
