We have been through a similar situation in our family a couple of times. Quick summary: My husbands sister died from complications of surgery at 26 leaving 3 small kids 6, 7 and 8. Her husband remarried but was found to be abusing/molesting the daughter a few years later, My inlaws who had tried to maintain a close relationship with the kids and be involved with their school, got a call one day from the school to come there immediately. Social Services had been called in when a friend of the girl told a teacher what was happening. The teachers told Social Services they were sure the grandparents would take her, which they did, they also soon got the 2 boys when the father went to prison and the stepmother, didn't want them on their own.
Fast forward a few years and the oldest son now has 3 children, and after the youngest at 2 walked across a busy highway while the mom was sleeping, Social Services began investigating them and found them to be unstable, violent etc. They were going to put the kids in Foster Care, but my mother in law again stepped in, and agreed to take all 3. The girls were 3,4 and 5 at the time.
My in laws were 66 and 68 at the time. They were given temporary custody by the State, but a couple of years later, when they found out the birth mother was trying to get her ex-stepmother, to get them as Foster Kids since not being related she would be able to get the stipend, and "share" it with her and her husband, my mother in law went to a lawyer and got permanent custody. Financially they struggled for years, only able to get Medicaid for the kids and after school care paid by the state and reduced lunches. I did a lot of research on their behalf and found out about the TANF funds. My father in law went to apply and when he found out that they would go after the parents for the money he got through TANF, he refused to apply, not wanting to put a "burden" on the deadbeat parents. I didn't agree with that, but I couldn't push him. We have tried to help as much as we could all along, and 2 years ago, when we sold our home we bought a much larger house and moved them in with us, so his parents could retire, which they finally did last year at 72 and 74. The girls are now 10, 12 and 13 and very secure and well adjusted. There is just no substitute for being raised by family who loves them, if that is at all possible. My mother in law has become a thrift store addict, to keep them and her in clothes. My husband and I now buy all their clothes and declare them on our taxes (father in law was letting the father use them for taxes, until I put my foot down and said no way)
We live in NC, so not sure how the laws differ from AL, but you should definitely be able to get Medicaid, after school care (maybe daycare while you are in school full time) and free or reduced lunches. I think they could have gotten foodstamps after they retired if they hadn't been living with us.
