Should I Request Gently Used Items at My Shower?

Sara

I'll be a FTM come December. I would like to let future shower guests know I'm ok with some specific registry items being gently used/secondhand. While i am grateful for the generosity of our family and friends I also want to be considerate of them.

Is this a good idea?

Has anyone else done this?

What items are safe secondhand? (Obviously not a car seat)

I was thinking they can let my mom or MIL know what they bought, that way either I or my husband can check it off the registry so we don't get doubles. Am I just making things more complicated?
