DS has ASD and gets stressed out by high-pitched noises and the kettle boiling. Our previous kettle made him moderately stressed, but slamming with enough force to rock the house closing the kitchen door was usually enough. That kettle broke and we are using my Mum's old one for the time being and it takes ages to boil and sounds really loud while doing it. I don't want a hot water tap or a stove-top kettle but I would consider a thingy that keeps the water hot all the time if I have to. My ideal would be another normal kettle that is quiet, I don't mind if it takes ages to boil so long as it doesn't make noise while doing it.
