No one buying from my baby registry!

Mj
My shower is in less than a week, and only 4 things have been purchased from it. I am very grateful for any gifts I receive, but I am worried that I will have an excess of things I don't need that will not be used (like a surplus of size nb clothing). I have a variety of items on it with all different price points ranging from $2-$150, so I don't think I am being picky. Has anyone else experienced this? Why do you think people are not buying from the registry?
