Etiquette on vow renewals

My husband and I got married in 2020 at the courthouse. We had both been divorced and we're slightly older and wanted to try for kids. We didn't know how long covid would be a thing so we just decided to do it with just our parents to celebrate. I thought I would be fine with that because I've already had one wedding. But as we watched a few of our friends get married, I found myself crying every time for the wedding I didn't get to enjoy with my husband.


We now have two amazing children and are incredibly happy with our little family. I brought up the idea of a vow renewal to my husband last year. He agreed to it, saying it would be fun to get our friends and family together for a celebration. We hadn't decided on a date yet, but recently I'd been thinking we'd do it in December of 2026 which would be 6 years after our wedding.
I've started looking into how to plan a vow renewal and realized there is not much information online. When I bring it up to family members, they look at me weirdly and say something along the lines of "it's only been 5 years". Is there some kind of etiquette that I'm not understanding?
I also just don't understand the etiquette surrounding vow renewals. Like is it okay to have a bridal party? Is it okay to have a ceremony or do they usually just have a reception? I guess I just need to know if there a specific difference that makes it a vow renewal and not a wedding.
