It's happened 3 times now. I think he's cleaning his teeth but then see he is trying to shave. I've ordered a toothpaste dispenser to stick on the wall. Wish me luck this works. I've also had the taps in the bathroom changed to the ones that you just press down and it goes for a little while. Another thing I've ordered is a hot pot so I'll boil the kettle to fill it then hide the kettle. That should stop him overfilling the kettle to make tea. It's dangerous as the boiling water spillsout of the spout. I'm using puppy pads which I cut to fit around the toilet. Hope some of this is helpful to someone.
