Maybe it's just for DSTV Now or for the school holidays - the channel number is a bit strange not being 312. I'm more surprised though that there are still kids programs left we are not already getting across 11 channels!

Normally when something is added for DStv Now only, it is labelled as Channel 100, not an actual channel number.
It seems that the new PBS shows actually outnumber the existing Kids content on DStv Now.
Channel 318 wouldn't be a bad choice for a kids channel with a heavy "educational" slant.
