What is happening with my client’s newborn grandson to cause his lung problems? Will this heal successfully? Is there anything more we can do to help?

This is a karmic problem and is one of past life interconnections between him and the mother. As you saw intuitively, she is, in effect, involved in the energy here as well, so doing the both of them together with your Protocol session will be especially helpful in allowing this interplay to be resolved. That is the key to nip things in the bud, so to speak, to prevent further difficulty and allow healing to proceed uneventfully. This has deep roots, but the healing being launched so far is doing what it needs to. You are adding to this through your efforts, and the work was already underway, so we think things will proceed smoothly from here. There is always the possibility of unforeseen complications, particularly in a medical setting, but this can be dealt with through further session work as well as ongoing prayer work, which is always a good idea to apply on a regular basis. So the family is doing all the right things here and there is no reason for things to worsen.
