I know what you are feeling! It is so hard to watch our little ones go through hospital tests. How nerving it can be.
My son had what your son will have, I believe. It is the dye that they inject into the body that will show up on CAT scans and MRI's, right? I couldn't find anything on the net about the dangers of it, until about two months after my son had the process done. He is still alive.

I did give him herbs that helped flush his urinary and kidneys: dandelion, marshmallow, lemongrass, uvi ursi. But since your son is nursing, maybe
you could drink these things and just prepare to use the bathroom, yourself, a lot!

Good luck with the testing! He is in God's hands, so do not fear.
