My best friend's sister wants to organise a baby shower for her, actually that should read she rang me up saying you're better at organising things you can do it!! 
My first reaction was, does BF really want a baby shower as it doesn't seem like her to want one - but more her sister & mum to want it...
So, what happens at a baby shower - I have never been to one?! How long are they supposed to last, who to invite etc....
If I can get some information, then it may make my 'job' easier!!
Thanks
