Nervous about having second child

I’m 20w pregnant with my second child — the first is 3 – and I feel a different kind of nervousness this time around. Of course I somewhat know what to expect now in terms of pregnancy, birth, and development (if all goes well), but 1) the shifting dynamic of having more than one child and 2) the anticipation of going through certain things again (sleep deprivation, colic, severe ppd and panic attacks, etc.) has me anxious when my mind goes there.

I know that I should take things a day at a time. I just think it would really help to hear about others’ experiences with this transition. There are lots of resources out there for FTMs, but I haven’t found much about being a second-time mom if that makes sense. 😂 I’d love to hear your insights!
