Visitor Visa for Parents - expecting baby

• Hello All,
  
  We are expecting a baby and would like our parents to visit. What documents do we need to send them for a tourist visa? Should I mention my wife's pregnancy in the invitation letter. Please suggest what all should I mention about her pregnancy. If anyone of you has a sample invitation letter, then I will request you to share that also. I will be greateful to you for your help.
  My father (he alone) was here on visitor visa last year also. He came on "single entry visa" and this time I wanted to apply for "multiple entry" for both of them. Will that be a good idea?
  
  Please suggest!
  Thanks in advance.
