School and baby sitting?

So I start school Monday, I’ll do 4 classes at school and 4 classes at home. I have no problem with that cause I have a son and I don’t like day cares. Well, Monday afternoon I’ll start babysitting from 2pm-12am. I’m not going to get any sleep, but I really need the money for my sons diapers especially since his dad only helps here and there. However, I’m determine to finish school. But if I miss one unexcused day, I’ll go to jail for 3 months and my son will go to foster care.. so obviously sleep is a big issue here...

If anyone wonders why I’ll go to jail :

Last year I was doing homeschooling, I took off a COUPLE of weeks after I had my son (c-section) because my teacher wouldn’t let me get on homebound. She didn’t even count the days excused when I was in the hospital having my son... so now it’s very critical for me to finish school with no absence days.
