Am I really do things to early?

Jamika
I'm 6 months (EDD 9/7)
My family said that I am planning things way to early. 
I've found a dr, found child care (my step mom who keeps baby's full time), have colors and things for my daughters nursery. All of which I thought was normal to have in place by time baby gets here.
I'm a new mom, I'm 24, want to go back to school to finish my last 2 semesters once she comes. I thought I was being responsible. I have my own place, own car (in my name), work full time. 
Idk what do y'all think? Do y'all have things together or should I really slow down?
