my child is now three and we recently got approved for ssi. however i just found a link on the social security page that says if a child was born prematurely weighing a certain low birth weight he/she would qualify. well my child would have qualified at that time, unfortunately my social worker had never mentioned this to me. does anyone know if ssi will retroactive pay for the time my child was born? or does the funds begin when the application was turned in?
