Does anyone have any tips on how to stop my dd from fiddling with the dials? it's driving me nuts - she turned on the tumble drying dial today on stuff I didn't want tumble drying and she's constantly changing the programme and water temp dial while the washing machine is on. Can't lock her out of the kitchen (it's open plan living), can't put a chair in front as she can move them, can't find anything on the internet to put over the dials. HELP!!
