Jesus wants me for a Sunbeam

After nearly a year in AZ, I've finally gotten a calling at Church. It was so nice to just be able to go to church each Sunday and not have to worry about preparing a lesson or keeping anyone entertained or what I was going to wear (who cares what you look like sitting in the back row of Relief Society). It was also nice not to have to worry about mid-week activities and what the kids or adults would enjoy doing while getting something spiritual out of it. However, those days are now gone. I have been asked to serve as the Sunbeam teacher in our ward. For those of you unfamiliar to the Church, this entails being responsible for the 3-4 year olds for 2 hours each Sunday. At least I still don't have to worry about what I'm going to wear, right? Part of the time they are in with a larger group of kids for sharing time (where they have a short lesson and talks by other little kids) and singing time (where they sing, obviously). The rest of the time I will have them alone in a small room to try and teach them a lesson. Yes, me and a groups of preschoolers in a room together. This can't be good. Let me also add, for those who may not know me well, that I'm not really a sensitive person or maternal in any way. I didn't have younger siblings to care for and I never babysat as a kid. I mean I have kids of my own, but other people's kids really aren't my thing (incidentally, some days my own aren't really my thing either). Please, please pray for me - I'm going to need all the help I can get!
