Participants are divided into pairs. Each pair produces a sound by which they can recognize each other. This sound should be created using the mouth (no clapping, etc.). One of the pairs plays the role of the baby and the other plays the role of the parent. The babies are then placed on one side of the room and the parents on the other. Babies are asked to close their eyes. Meanwhile, the person playing the game changes the positions of the parents with a hand gesture. At the leader's signal, all parents start making the sounds they have identified. Until all babies find their parents, the parents do not move and continue to make sounds. When all participants find their partners, they open their eyes and applaud each other. The game is played one more time with the people playing the role of baby and parent switching roles.
