Music Teacher?

So...how does a MUSIC teacher teach music without a voice???? That is a question I have pondered ever since I started teaching. I typically lose my voice at least once a year...It started Monday afternoon. My speaking voice is lower and a little in and out, but it's the singing voice that is just not pretty!!!! Yes, I am teaching little munchkins to sing their Christmas program songs with no voice! So, how do I do it???? With a lot of giggling(by the students and me), a lot of frustration, and a lot of..."Listen to the piano on this part boys and girls"! Oh well...it feels like it might be coming back already, so hopefully it won't be a long term thing...Oh, and did I mention that I am leading worship at church this weekend! HA!
