If I know the exact number of kids I just do a lollypop in each layer and they go off and eat it while the game continues. Each round is completely random. I may or may not have deliberately stopped on a couple of toddlers/babies early in the rounds

I've seen it where they had a list of who to stop on in order because they had specific prizes in each layer. Was dreadful. Cos of course they stop the music but the parcel went too far or something so they'd say.. no this one's for Johnny. So the poor kid who actually had hold of it had to pass it back.
