Do you have a huge fear of your first born feeling left out or feeling like he/she is feeling replaced in any way??

I'm pregnant with my 2nd child and have this fear that I have to do everything equally for each child or I'm gonna make it seem like the first born is being "replaced" or left out. For example, I'm getting the baby's room ready and there's a sign on my first born's door. I'm gonna make a sign for the new baby's door and even the size of the sign possibly being slightly bigger makes me freak out about my first born not feeling loved or something!! I feel awful for what I know is dumb and irrational. But I can't help it. How do I stop feeling this way? He's only 1 so he has no idea what's happening.
