Dear Kaycey,
I also am inept in thinking of words to provide you with comfort. You came to the right place .As a caregiver too I may not always post but have found support in all these wonderful people's words.Your husband has to come to terms with a lot right now and no offense guys aren't the best communicaters to begin with.Enjoy your son maybe the joy your husband can see through your son will help him. There are several communication devices maybe if you get one your little boy can have talks with his dad. It's very entertaining for a child . I work in a hospital although i work mental health thereis another side where freguently i see young people with these machines some with there children on their laps. I wish you all the best. You'll find the strength somehow.
Take care
Diane
