The problem with 98% of "Christian" children's programming is second commandment violations (2CV). You run into this problem with books as well in broader Christendom, but for the most part you can find reformed publishers that are committed to not putting 2CV's in their books. I have yet to find a true reformed media company that produces quality content without 2CV's. The options are quite limited and with 4 children ages 12, 8, 6, and 3 I like to think I have nearly exhausted the search for quality, Christian kids tv programming. I will add you are much better off reading to your children on the Lord's Day than putting on a video. As noted, there are much more good book options for young people. With that said, here are a few we;ve watched in my household and my kids have actually enjoyed and kept their attention:
As has been mentioned, Torchlighters is a favorite in my household. The kids have literally watched the episodes over and over. They even enjoy them so much they had my wife track down DVD's in addition to streaming so they could watch in the van on the commute to worship.
Moody Bible Stories is another the kids like and they are OT narratives so no 2CV's. They also treat the bible narratives with proper reverence. This is the other problem with children's Christian programming is that it gets so dumbed down it becomes irreverent. This is not an appropriate way to treat the holy things of God.
The animated
Pilgrim's Progress is good also.
Lastly, Pastor McCurley's teaching through the
WSC is quality. I believe Pastor McCurley's intended audience was children so it is done to their level and has just enough illustrations to hold their attention well.
Beyond these, my children actually enjoy documentaries. One of their favorites is Banana Man by Ray Comfort. They've watched this like three times lol. I know Ray Comfort, but I found this to be surprisingly good and I literally wept at the end. They also liked the
Puritan documentary from RHB.
