Full grants for single parents to go back to school - don't want student loans!

Can you really get grants for single parents to go back to school? I have a 5 and 3 year old and I was thinking of going back to school to further my education. I don't have savings and I don't want to take out debt because I've heard horror stories about single mothers who cant pay off their student loans. I was wondering if there were any grants for single parents to go back to school which offer full payment for the course and all the costs associated with it. I was a bright student and I think I've still got what it takes to get a good education which would help me get a better career. Look forward to some constructive replies.
