I don't think I will even try to console you, because we all know that there is no use. You never really got to know baby Joshua, but you were still his mother, and he your son, and there is no greater loss than that of a parent's child. I cannot even imagine. All I will say, is I am a firm believer that things happen for a reason, God has other plans, and though it seems so unjust and simply not fair and uncomprehendable, I don't think we are supposed to understand really. You cannot have the good things in life without the bad, and as much as I know it must hurt God, there has to be bad. I figure He only knew that you were strong enough to carry on, and that you have a loving partner there to help you through it as well.
Adding you to my prayer list. In both my and my family's thoughts.
