A test for JWs, from God?

Children of Jehovah's Withnesses sometimes die because their parents' religious beliefs are against allowing people to have blood transfusions. But what if it's nothing more than a test from God? To see if you'd place your own child, whom you are fully responsible for, before God? To see if you love the life of your child over your own desire to presumably please God? Perhaps God presents these situations as a test of love? Perhaps by allowing your child to die you actually fail this test, and are sent to Hell for placing your own desires before your child?
