For a year now, my husband and I have been teaching 4 and 5 year olds during the Wednesday night prayer service. We have a program called King’s Kids and it’s a ton of fun! I write up a lesson each week (with help from TONS of info and inspiration all over the internet of course!) and we do verse memorization, arts and crafts, learn songs, and play silly games. It’s not on Sunday, but it’s close enough to “Sunday” school! :-D
