Given the amount of money you receive it seems obvious that you are only receiving SSI not SSDI. In order to receive SSDI you had to have wotked about 11 years or 44 quarters. If you receive SSI the children do not receive any benefits unless they are also disabled. Also SSI benefits are not determined by what your husband makes. It is specific to the area where you live. For instance in New York State the benefits are increased because NYS contributes to the dollar amount.
