Singing time

So I found out tonight exactly what my calling is. They want me to start doing singing time with the Nursery kids, yes all 2 of them (3 with Scout)!! The primary chorister doesn't have the time so they called me. Well, this could be interesting with my singing ability that doesn't exist! I already have a few ideas, but if anyone has any ideas they would be greatly appreciated. I need something that is fun, and not just sitting and me singing to them (we all know with 2 kids that is how it will be). One of the boys struggles with some things, and I want to get him up and involved. Anyway, I am excited about it, and it should be fun.
