Find your own child
	Take someone else's child
	No vocal clues are allowed

All the children are tied up inside bags with only their arms sticking out. On the whistle, the parents have to find their own kid without being able to look into the bags.
Once they think they've found their own child, the parents must take the bags across the finish line. Only when they're across the line can they open the bag and let, hopefully, their own child out!
