Bottom + Towel = Despair

One of the first things I heard this morning stopped me dead in my tracks. It was my husband. He had just opened the bathroom door and in a shocked voice said to the 4 year old ...

"Have you wiped your bottom on this towel?"

Do I really have to spend this afternoon heading up a masterclass in bottom wiping for the child who has been toilet trained for two years whilst the child who is currently mid toilet training watches on?

I despair, I really do.
