Super nervous

Morgan
I'm at first time mom as of Friday, my sweet baby boy was born. But ever since we got home I'm just really nervous to be left alone around him, I'm only 19 so I don't know much about babies or what's normal and what isn't, so when I'm left alone I'm terrified that something will happen and I not know what to do or if it's supposed to happen or not. It just makes me feel like a bad mother already since I never wanna be left alone around him  I love my son to death but I'm just nervous 😕
