"Don't, don't, don't bite your friends!"
Yeah, Yo Gabba Gabba and Backyardigans were two of our "backup" shows for times when our daughter wanted something other than Dora. We were really scrambling once we realized they were all gone overnight. (In the urgency of the moment we stumbled into "Curious George", which I have issues with. I hear good things about "WordGirl", though I get the impression that it's got a slightly older target audience.)
