Do I have a good job to take care of my baby? ?

I currently work at a diner a waitress and Aeropostale as a clerk. I get about $316 a month including child support. I also get about $100 a month working in my uncle ranch. Then I get money for paintings I do which averages out for about $40 a month. Making my average monthly intake $456. Also my child won a contest so we won a years supply of dipers so don't include them. I only want to know if I'm getting enough money this year. Also I'm in high school so I live with my mom so I don't pay bills.
