There is a game where you buy several different kinds of baby food (different flavors). Then you pass them around and people can smell them, look at them, even take a TINY taste using a Popsicle stick dipped in (clean one for each person). Then they have to guess what the name of each baby food is. Some, like corn and the meats or meat sticks are easier to identify. But things like Tutti Frutti Dessert and other combos like that are hard to figure out.
the key is to soak off the labels of each one, after you number the jars and write down an answer key. Just be sure not to soak off the numbers!
There is also a game where you have rolls of toilet paper and each person takes as many squares as they think will go all the way around the mom-to-be without overlapping. The person who gets closest wins.
I have also seen a race where a number of baby bottles were purchased - one for each person there. The bottles are filled with a beverage (generally not alcoholic or sparkling) and the nipple is put on the bottle. People race to see who can empty the bottle fastest. At the end, the Mom to Be ends up with the bottles, so she is all prepared for when her baby needs them. Or they can be washed and donated to a charity if there are too many bottles.
I have seen it with full 8 oz bottles, with 4 oz in each bottle, no matter teh size, and with 1 or 2 oz in the bottle, no matter if it is a 4 oz or 8 oz bottle. It goes MUCH faster with just 1 or 2 oz in the bottle.
I have also seen it where the contestants can choose coffee, tea, punch, water or whatever in the bottle.
It is nice to ask the mom to be if she is using regular bottles, the ones with the disposable liners, or some other kind.
I was at one baby shower where one game was for everyone to take markers and see who could decorate a nursing pad in the most creative, or artistic, or whatever way. There were different criteria, such as number of colors, had to be abstract, had to look like an animal, had to look like a food, had to look like ??? All it took was a box of disposable nursing pads and a bunch of markers. (I thought this one was really strange, esp after I saw some of the things people drew. Anyone ever see a nursing pad that looked like a penguin?)
I DO have a good punch recipe. You take a can of frozen juice concentrate - white grape raspberry if you want pink, white grape peach if you want a lighter color, whatever flavor you want. Then you pour a 2 liter of lemon-lime soda or ginger ale over the slightly softened frozen juice concentrate. Mix it up and it makes a great punch. And it is VERY easy, and you can adjust it to whatever your tastes prefer, or if you wanted to, to a color scheme depending on the frozen juice concentrate.
HAve fun with your shower!
