Nervous about upcoming I-751 application

I’m going to be filing ROC end of may/early June, and I’ve heard a lot of people say it’s a breeze compared to the initial GC application process, which I’m sure is true but I still feel really nervous about it. My husband and I have been together six years, just had a baby together, and this will be the third time we’re proving our relationship to USCIS since I came in on a K1. I’ve been keeping track of all the relationship evidence to send off for our application; tax returns, car titles and car insurance with both our names, lots of photos of us together with our child and family, boarding passes and photos from our vacations, rental lease, utility bills and bank statements addressed to us both, proof of our shared debit and credit accounts, our wills, vet receipts, baby’s birth certificate, mail addressed to us both at our shared address and some more stuff I’m probably forgetting.

Even so I feel like that’s not enough evidence compared to some other people, I’ve seen some folk send up to like 500 pages worth of evidence, which we don’t have. I obviously feel very confident our marriage looks legit, but at the same time I don’t know if we have enough paper evidence. I’ve also heard horror stories of uscis denying I-751 applications because they claimed to send out RFEs or schedule interviews which the applicant never received, so I’m also going to be so paranoid I’ll miss a notice.

Maybe it’s just my postpartum anxiety but I just feel so nervous about it and I’m getting scared of the worse case scenario where I could be denied and our little family gets broken up.
