And as part of this there is a fun sing-off between the boys and girls.
The competition is usually judged by Mama, Papa, a member of staff or a visitor but this week Mama invited one of the kids, Charity, to pick the winner.
It wasn't easy, but she came down on the side of the girls - who were clapping and cheering at their victory.
Here you can see her making her choice and the two choirs she had to choose between!
