I can understand that this couple does not want to lose their baby.
Doctrinally: some people just come to the earth to receive a body and, if one of
these sensitive souls dies in infancy, they are assured a place in the celestial
kingdom. The blessing was apparently realized in the prolongation of the little
one's life and the shrinking of the tumor. Time to await events. It
might be useless to point this out but it seems to be a win-win for the baby.
I just hope and pray that if it's the Lord's will for her to survive
that it will occur. But if by chance it does not then make the very best of the
days she has and there will never be any regret. I, for one, hope she survives
and lives to be a Mother.
