Fair disability for Stay at home Moms

I am a disabled Parent. I only get a low amount due to staying home with my older children. My oldest is Autistic and because I stayed home with him and taught him everyday, he is a college graduate holding two jobs and is a amazing person. When I became disabled in my 40s I was told I don’t get much to live on because I don’t have much work history. I feel like I was working everyday! Now my last minor child barely gets anything because I have a work history that is so small and until my husband turns 62 I can’t use his work history. I feel like the core values I instilled in my children by staying home with them was a job and my minor child shouldn’t be punished for the fact that I took time and effort to raise all of my children. I am 44 and had planned to work until my retirement like everyone else but life gave me another hand. I have done everything right, worked hard, raised 4 great children and still feel so left behind by our government. I did work and I had one of the hardest jobs there is. I know have to figure out how to live on 1100 dollars a month because of my disability. This life is not what I wanted for my youngest child and now I’m powerless to better it for him. Please help those of us who did work but never got to clock out.
