Leading worship for children is not the same thing as leading worship for adults. Yancy (not Nancy) shares four tips for leading worship for kids.
I really liked this one:
Ask questions that demand a response.
This is one of the easiest things you can do to engage your group. Because you are asking them to respond verbally or with an action. This can range from giving high fives at the end of the song or repeating a phrase to each other. It can be a shout to create excitement or even lyrics from the song you’re about to sing. Don’t just state what you’re going to do. Ask them questions to get them engaged in what you’re doing from the beginning.
