Carla, My son, Jason, who just turned 1, was diagnosed with salt wasting CAH at 1 month. He had problems with his formula causing diarhea while being stabilized in the hospital after being diagnosed. We found that Alimentum worked the best and is made by Ross Labs. It is very expensive but he gained weight well and had little spitting up. He was on this formula until his first birthday. We now give him whole milk with no problems. Good luck. Jamie K.
