Is this just a me thing?

I was so excited for my son to get here, first baby. So exciting! Pregnant with our daughter and now I'm super excited for her, but at the same time I feel kind of Eh about this pregnancy. I feel like I'm not as excited for her arrival, in 8 weeks, and it makes me feel all, well, eh. IDK how else to describe it. Maybe it will all sink in that we are having another baby when we have our shower. I hope this goes away and I can feel the same excitement with for Atleast some of my pregnancy.
