Visiting Rules

Do y’all think it’s rude to write a list of our expectations for our visitors when baby is born? I want it to be made clear to any and all visitors that they are not allowed to just come in as they please (without telling anyone), that they need to wash their hands, and that they may not kiss my baby under ANY circumstances. You would think this would be common sense to most.. but people surprise you. Should I write out a nice list and text it to everyone? Should I post it on FB? Is that too preachy? I don’t know what to do lol
