Quoting 2 Baby Girls:" I let all my kids watch sponge bob. 2, 3, 4, 6. They watch a bunch of other things too (the 2 year old isn't a big fan). We don't watch a ton of TV overall though. 1/2-1 hour daily."
Quoting DifferentDay:" 4 n 2 n not anymore. There was an episode where it was clear singe bob was being a proctologist n shoving something up Patrick's butt. That put an end to that show in our house."
