First of all your husband needs to change his attitude and if wants no part of your son's life that is his problem don't give up, blood is thicker than water and you have to know your son loves you, but he's hurt and maybe you need too take the first step in talkinng to him and letting him know you made a mistake and you want to make things better and that you want to be part of his life, grandpa will come around once he sees that grandchild......................A mothers love is never forgotten....................and your children always need you no matter what, they just sometimes find it hard to accept it and act on it.. Good luck and God bless
