Picture the scene. It's nappy washing day and everything is going well. Younger one is in a fresh clean nappy, the weather is perfect of drying and they are all in the washing machine.
Everything is going well when one of 3 things happens. I mean ALWAYS happens..
Number 1
I forget one nappy which is wet and smelly and has to wait another 2/3 days to get washed
Number 2
It starts raining. As any cloth nappy user will know, it's hard getting nappies dry inside when your heating isn't on
And at number 3
The poop-splosion. Obviously the youngest ones favourite. And a poop-splosion will ALWAYS happen just as you have turned the washing machine on, so again it has to wait another 2/3 days to get washed
If I'm feeling really unlucky then all three will happen but I'm guaranteed that one of them will
