I think regardless of how hard on someone it is, they can still support the dying loved one.
OP I think at the least, your DH needs to go spend time with his mom. Im sure a huge hug would do alot for her emotionally. Im sure shes trying to shield everyone from the fear of her impending death and to hug her baby boy would do alot for her in means of comfort. He could just go sit with her, talk about how great the kids are doing ect..happy things. Even just being there to hold her hand.
