For most of us dad's the only routine that we have in our lives is grabbing a beer and pie at half time at the footy. Or maybe it's the proverbial shower, shit and shave (usually in that order, this is a debate for another time and place).
One of the most foreign concepts to me as a dad was that something as small as C would benefit and more importantly understand a routine. But they are just little routine machines. From the moment they get up (uncannily the same time every single day, I don't even need to set the alarm clock anymore) they want to do exactly the same thing they did the day before.
