Congratulations on the birth of your babies.  My son is now 16 months old and I felt the same way when he was diagnosed at 8 days old.  It does get easier, I promise.  It sounds like the doctors are just trying to get your babies dosages correct and that is why their potassium levels keep climbing.  My prayers are with you as I know it is very stressful.  Quick question, are your babies boys or girls???  You didn’t say in your post and I am just curious.
