Single Mom Just Adopted Two Siblings

My mother just adopted two children, 3 and 4 years old in order to keep them out of the system. She is not rich and she has four children of her own, so she does not have money to spare for clothes and car seats. The kids came with nothing except a stuffed animal for each of them. My mom just flew all the way cross country to get them and that alone cost my mom $1911.95. My mother has one child in college she is paying for, one is severely disabled, and one is disabled, but still functioning normally. These kids are not foster children and so the state will not help out with needs. This was a signing over of parental rights due to parents going to jail. Anything can help. We just want these kids to be safe.
