Our Child Care Centre has a dancing teacher come in. I don't pay as my Kids do not attend on the day she attends. It was an extra $2 or $3 I think. The Dancing Teacher also helped out at the end of the year with the Christmas Concert, as in supplied costumes and did the 'choregraph' for the kids. She was good, so when I did pay (when my kids went on that day) I didn't mind. They only did it for the older kids though.
They have incursions like the museum or the farm animals people or lizard man, which we don't pay for, they are funded by the Child Care Centre.
