What can I expect when it comes to baby number 2? I am not pregnant but I want to be but I'm very scared like I already know the pains and everything that happens. And I had a c section with my first I was thinking of Normal birth with the second baby. What are some things that come with the second baby.

I'm scared my second one is the complicated like my first

My first is a light light sleeper and cries a lot and as a baby he would cry all day so I'm scared to go through that again.
