Praying for him. Both of my boys had the milk protein allergy and ended up on Nutramagen. I researched it the second time and found out it is covered by my insurance. It's covered by some insurances with a prescription. The trick is that it doesn't fall under pharmacy benefits, it actually falls under durable medical equipment benefits. If your son stays on it make sure to call the insurance company and tell them to look for it under durable medical equipment.
