Can I teach preschool?

So I've been doing this Children's Ministries director thing for about 4 months now. The first time through, I had a hard time getting someone to teach the preschool Sunday School. This time, I ran an "ad" in the bulletin for about 6 weeks with no volunteers. Then, over the last week, I've had 4 people volunteer to teach. 4. It's feast or famine, I suppose. Now I just have to convince them that they'd rather teach children's church. :)
