If you don't see a code on http://www.roku-channels.com/
in my experience the channel can be found on the ROKU Store or it just doesn't exist.
Go to: http://streamfree.tv/apps/roku-private- ... nd-family/
and of the channels listed you should add NowhereMan Private Channel Code H9DWC
I've added all of them, but NowhereMan has the better programing.
NetFlix has a great selection of kids programing, specifically Barney.
You should also add the Disney channel, http://www.roku.com/roku-channel-store#7
if you have a six year old they won't mind the clips.
I used to subscribe to BabyFirst TV, but some of the programing is available in NetFlix.
FYI, Don't add my channel to the Roku your kids will have access too.
