I think its a nice idea to have one. I dont know if I'll have one. Most of my friends are idiots, but maybe I could just invite the nice friends and not tell the moronic ones. Actually for me it would be mostly family probably, lol.
Anyway, it would definately be nice just to catch up with your friends before baby arrives and let them shower you with love and presents and give you lots of attention. It will probably be a bit tricky to have everyone over once baby is born too.
Ooo now I am excited about having a baby shower even though I wont be doing it for a few months yet!! hehe
