Baby Shower Registry

Mama’s who have already had their shower... How long before your baby shower did you notice guests purchasing items from your registry? Mine is a little over 2 weeks away so there’s still plenty of time. But no one has purchased anything from it. Don’t get me wrong, I’ll be grateful for anything I receive, but I’m worried I’ll be gifted things I already have/won’t use and that I basically took the time making a registry for no reason 😢
