How I got started

First I started with the Family time organization and their outline for Family Nights.

We picked a very simple theme song, "B-I-B-L-E" song from a children's CD we own. So we picked a day that would work for our schedule and one that would work consecutively every week. Since we started when the twins were almost two years old, time expectation was around 10 minutes total.
We played the song and then quickly explain what we're going to talk about. I planned a short activity with a main topic and then end with prayer. If the activity required more time, we'd pray mid-way during the activity and then finish it up later.
I wrote a brief explanation of what we did every week. I'm glad that I did that because now I'm logging it all here for others to use.
