FTM getting scared. tips PLEASE

young mom having my baby in a few short weeks and I am prepared and have everything I need for her. It's starting to feel really real and I'm unsure if I even know what I'm doing..I'm a single mom btw so I won't have any help. Any advice or tips on anything for caring for a newborn will help tremendously. When should she sleep and how often should she eat? Should I wake her up to eat or let her let me know when she's hungry? Any other tips too please!
