Hi there - I also haven't been to one before and can't wait for mine on Saturday. MIL and SILs are organising.... I am helping with games and we are having women and kids only.... just cause DH wants to go the pub with his mates LOL
SIL sent out invites and getting RSVP - I did a list of my friends andfamily I wanted invited (even though I knew most of them can't come as they live far away - I think it's nice to invite them !) and SIL did the ones I forgot on their side of the family. We are just have an afternoon tea (with grog for them of course!!) with nice food and drinks (SIL said on the weekend she had found some great mochtails for me YAY!)
But whatever you want goes really - its your day. I haven't done a register or anything, just gave a list of things we might need to SIL who tells people who want to know - really for us some people are coming from far away and them being there is gift enough for me. We also suggested if people are stuck, gift cards from Big W (which can also be used at woolies) so that if we get cash strapped down the line and run out of food, etc we have the cards to use... (DH idea!)
I hope you have a great time... enjoy the company of all your friends and being spoilt rotten it mightn't happen again for a while!!!
Ps - MIL suggested 4 weeks before birth date in case she decides to come early!!! But I have heard of other having them just before their due date..
