Surprise Baby Shower

I found a site that might be of some help:

This may be of some help.

I always like the one that everyone is given a clothes pin (or tag of some sort) to wear when the come in. Then the rules are that no one is allowed to cross their legs during the playing of games. If you catch someone crossing their legs you point it out and get their clothes pin. The one that has collected the most pins at the end of the party wins some little gift. I usually end up winning that one. LOL

Heres my two sence

Use this site to get invitations. Its free and you can pick your own invite. So it can go with whatever theme you choose.

i say go with homemade favors again you can go with your own theme such as make home made soap. make white soap and buy food coloring pink or blue and then use items like cookie cutters to poar the liquid soap and make it harden in the shape you want.

Hope this helped.

The best game I ever saw at a baby shower was the clothes hanging game.
The goal of the game is to have the participants (one at a time) try to hang as many clothes on the clothesline as they can, while at the same time holding a baby and talking on the phone.
What you need:
A long strong rope to act as a clothesline.
Two volunteers to hold the clothesline up.
A cordless phone.
A doll that can resemble a baby (or a 5 lb bag of potatoes wrapped in a blanket).
A basketful of clean, dry laundry. Try to have it all be the same stuff, like dish towels, or socks.
Lots of clothespins.

Each contestant has a minute to hang as many dishtowels or socks as they can while they talk on the phone and hold the fake baby. The people in the audience are supposed to make conversation with the person, as though they were the phone conversation the person is having. If you want to make it super tough, have the people holding up the clothesline move it around a bit.
It was so much fun. I dropped the baby (potatoes) twice when I played.
