The JW religionists have all their bases covered:
If the child dies (as has so unfortunately, often, and needlessly been the case), then it is thought to be Jehovah’s way of providing an opportunity to show faith, trust, and loyalty to Him in awaiting a resurrection while, in the meantime, supposedly being the impetus for the parents to keep preserving (enduring) in the WT religion down “to the end” so that they might (hopefully) one day be reunited with that child. (Of course, one ridiculous aspect of it is that quite often the child had to end up dying in the first place due to the WT’s extreme fundamentalist and cruel interpretation regarding blood transfusions!)
Yet, if the child is still currently living, then it is thought of as apparently being an opportunity to show Jehovah how one’s faith and comfort in Him (a.k.a. the WT) can help one to COPE with the trying situation at hand.
So, in other words: Whatever happens, trust in Jehovah (i.e., the WT) to make everything all better.
