Nervous 😟 😔😔😔

I am a little over 28 weeks pregnant & I just started thinking about things. When I had my first son I was 16, he will be 8 years old this year. I never seen myself having another baby. Well here I am having another one with my husband & I’m happy but Very nervous. I haven’t dealt with a newborn in forever. He works overnight and I work first shift. so overnights I will be alone with the newborn. With my first son my mom was there to sorta help me with things I wasn’t familiar with. I know I’ll be okay in the end some how, some way but I am just nervous. 😭😞
