Children's Church

OK, so my congregation is a small, growing one. There's not many LCMS Lutherans to begin with and many people leave when they have children, so we haven't had any families until recently. We are now at a point that we are looking at starting a children's church and I jumped on board, since working with children is the way I feel most comfortable serving, although I have never had to start a cc or Sunday school program. Of course I am getting assistance from my pastor and his wife, but am being given a bit of leeway. Any thoughts or suggestions?
