Anyone else super nervous for some reason the second time around?!

My son was born in Sept of 2015 he wasn’t so much planned as he wasn’t prevented but this one due in Jan 2019 was planned.

I am so incredibly nervous about this one. Not nervous for baby but nervous that something is going to happen. I’m trying so hard to remain positive just like I was with my first and very much so looking forward to having another baby I’m just so nervous. No idea why?!!
