You have 2 kids but don't have health insurance on you and your wife and only limited on your kids??????
1. Get a 2nd job
2. Your wife can work part time evenings/weekends
3. Stop smoking, drinking, going out to eat, etc.
Then you will make enough to provide the basic amount needed to responsibly support a family. Right now you are 1 small accident away from ruining your kids life. If you think a government handout is the answer then you are aready too far gone!
