For our Children's expenses

Hello,
I am the mother to one son, Keelan Matthew. He was born with a birth defect called craineosynistosis and chiari malformation, and is one years old, he has had a very major surgury this month, and had an infection a week after he was sent home, leading to a return to Mayo for another week. He has been doctoring at mayo since he was 3weeks old, in Rochester MN. It is a three hour drive from our home, and we have been there at least every three months, and up to once a week for five weeks in a row. We are a very young family, we have four children and our doing our best to make ends meet, but that is a lot easier said than done with a family of six and three sons that are sent to Mayo, often. I also have two step sons that doctor up there for birth defects and surgeries. We are just a young family trying to make it and be responsible for our children, we really need help though, we are unable to afford all the medical expenses! I have never asked for help and I don't want to be gready, every little, or big bit helps.
