I arranged my own Shower, but i had fun doing so!
It was very casual, just friends & family to my house for finger food, games & presents!
(If there are some specific gifts you'd love to receive for Bub, make a "wish list" & post it with your invitations...!)
A few games:
Pin the Dummy on the Baby - printed a picture of a baby crying, then printed a bunch of dummys & cut them out.
Word game - when everyone has arrived, give them 3 pegs each & tell them the 'word' (eg. baby) - they're not to say this word, but if the do, the first person to hear them takes a peg from them, the person with the most pegs at the end of the shower wins!
