My daughter's baby shower's theme was Ducks. She doesn't know the gender, so the colors were yellow and green. The favors were gourmet mints in a yellow and green organza bags and we made duck chocolate taffies. We played Baby Bingo, where everyone filled in a Bingo card with items they think she would receive. As she opened her gifts, if someone had that item on their card, they crossed it off. There were six winners, each was given a small Yankee candle, wrapped in yellow and green tulle. We also played Guess How Many Sweet Tarts. I filled a baby bottle with Sweet Tarts (one of my daughter's favorite candies). I printed out slips of paper with lines for the guests to write their name and their guess. They were all put into a bin. The person closest won a gift card. We played Who Knows Mommy and Daddy Best. I had chosen questions relating to my daughter and her husband...what is their pet's name, what high school did each graduate from, who is their favorite Disney character, etc.
After everything was opened I asked them the questions. Whoever got the most correct, got a gift card. We also had a door prize winner. I bought tickets at Party City and included one in the invitation. Everyone was to bring their ticket with them and put the stub in the bin. We picked a winner, who received a gift card.
Oh, forgot Baby Price Is Right. I filled one of those storage bins with baby items...a pack of diapers, wipes, powder, onesies...I would pick stuff up whenever I went shopping. I kept track of how much I spent. I had the bin on display for the guests to look over along with a printed list of each item in the bin. They had to guess how much everything cost. Whoever can closest won a gift card.
