My sister is having a baby and I wanted to host a baby sprinkle. Not a full meal, not during meal hours, just some dips, veggie trays, sandwiches, and, of course, cupcakes. My apartment is not big enough. Can I host the party at her house, where we would have enough room. or does it seem like she is hosting the party, even if she does not lift a finger? We cannot afford to have it at a venue with the wedding coming up and our budget being as tight as it is. I know I don't have to have a small shower for her, but I want to. Also... would PRIVATE facebook invitations be appropriate for a gathering of this nature and informality? Or would that be considered tacky?
