"Do you need to go potty? Maybe yes, maybe no; why don't you sit and try to go?" has been immensely helpful. There's a Daniel Tiger song for every situation!
Haha this was my very first thought when Daniel Tiger was mentioned. "If you have to go potty, stop and go right away..."
(I was working on an RTSP streaming video client and all I had handy as a video source for VLC to stream was Daniel Tiger's Neighbourhood. It only took a few days because ffmpeg is awesome but this song is now burned into my brain...)
