I separated from my husband and moved in with my mom in July 2023, divorced Sept 2023. I have no income for 2023, have 2 kids. Do I file or does she claim us all?

My kids get SS Disability benefits from their father, but I am legal custody parent and he is in jail. I am not working yet so I can't get child tax credit. Can my mom claim all three of us on her 2023 taxes as dependents?
