What a clever little man!!!! Soon you won't have to do washing at all! lol
When I was telling DH, I said that if we start to hear the washing machine we'll know who it was... but we do turn it off at the powerpoint, so until he can reach that, washing is mummy or daddy's job
He does also help hang the washing on the clothes airer when we use it, and take them off again when they're dry!!
