Planning for baby #2

Any ladies here excited and also maybe a little scared of having a second child? I have mixed emotions and wondering if anyone else feels the same.. I had a scary experience with PPD after my daughter (she’s currently 18 months) so maybe this is where the anxiety manifests from. I believe it’s totally okay to have just 1 child, but I do think it’s great if they can have a sibling too. Just wondering if I’ll ever be 100% ready to try again or this is normal to be a little nervous?
