Get medicade and wic. It will help a ton. Free fórmula and food. Free medical bills. Baby's have wic till 4 or 5
It all depends, go get a job yourself. Don't live beyond your means and sign up for all the helpful programs you can. Have a baby shower or 2 and do what you can. It's going to be tough but you just have to start being an adult and making it happen. Best of luck to you!
