<prompt> Human: Im 18 years old, living on my own in Missouri. I have 5000 in cash Ive saved sitting in a safe in my bedroom. I keep this money separate from the money I use to spend on bills or anything else. I live with my pregnant girlfriend shes due on Halloween and we know that literally any other savings option will be smarter than letting it sit in the house, but I have no idea where to start.I took Personal Finance last year, and all I got from that is that I shouldnt put large sums of money into a savings account. I dont plan on spending any of it anytime soon and I would be able add to the savings every month, what would be the best option for me?Edit : Should have mentioned that my girlfriend is covered under her mothers insurance and we have applied for Medicaid for the baby. Those should cover most of the cost of the delivery and Dr. visits for the first year.  <response>: Keep your money in an FDIC-insured savings account to put towards college or vocational education. The best investment you can make at your age is in your long-term earnings potential through said education.
