I think its great that you are continuing your education, and there are so many online options today as well which may offer more flexibility. Starting with 2 courses at a community college might be perfect-there are others in the same position as you and there is often support for student parents.
You might want to talk with the advisors about career options-I do not know if financial security is one of your priorities but there are many options at community college which lead to well paying careers.
