My 10 year is in charge of games and the sweets table, one game is pregnant twister. The kids would put a balloon under their shirt and play twister, whoever loses their balloon is out. Then we have measure mom's belly, 40/60 raffle $5 labour guesses (date, weight and time) 40% goes to the winner and 60% goes to baby, and guess price items on baby supplies.
We're having a co-ed shower so we'll be trying to incorporate as many team/partner games as we can to accommodate all the guests. A fun on we've done before is the blind folded baby food feed! Teams of two, one person gets fed the other feeds. The one feeding is blind folded and isn't able to see, first team to finish their jar of food wins. We used apples and bananas as they taste better. Haha
