Is it appropriate to have a small registry, all items under 20$ for a small 2nd baby shower?

I did a small registry for my small ”baby sprinkle”. About 20 people are coming and I have about 30 items all under 20$ on the registry. I feel weird registering for gifts for my 2nd baby, but I read some articles about how people like to have a guideline for a gift of they’re invited somewhere. Is this appropriate or do you think people will be turned off by seeing there is a registry?
