No baby shower, #2

Lissa
We are not having a baby shower as this is our second. We have the major baby supplies from the first time around, but still need some things (i.e. bottles, milk storage bags, sleepers, DIAPERS) I would love to stock up so I don't have to be buying these things after he's here, but don't have the money for that. Is there a polite way to let family know we have a registry if they want to contribute? Anyone else need supplies but not having a shower?
