When you mail out your invitations be very clear how they are addressed to. If it is just the parents then the outer envelope should be addressed to "Mr & Mrs. Joe Smith". The inner envelope should say "Mary & Joe". If the whole family is invited address it to "The Joe Smith Family" then inside "Mary, Joe, Susie & Joe Jr."
As for your friend... invite her. Let her make the choice.
