Carol:  There is so much for you to learn, go to CARESFOUNDATION.com to read up on CAH.  Your son may have to step in and take control of your grandchildren’s health care.  Its a lot, but between you, the docs, the parents and our Lord, you will be fine!! Your grandson will need diligent everyday care and your daughter-in-law will need lots of support and to stay on her meds.
