We love our IKEA kitchen but it only fulfils half of your requirements. We have found it really sturdy and all my DS are climbers and testers-to-destruction and it has so far withstood their rough handling (DS3 loves to stand on the very top giving everybody heart failure!) Unfortunately it is very limited in the buttons/switches/lights/sounds but has got some nice sturdy doors which are often very popular!
I want to get a play kitchen for my DS (aged 3) for Xmas, has anyone got any good recommendations? His dad does all the cooking in the evenings and I think he would enjoy trying to copy him etc. I think that one with some buttons/switches/lights/sounds etc would be the best fun for him (he is autistic and loves pressing buttons, switching switches etc). It would have to be robust as he is a climber and a great tester-to-destruction of anything in any way flimsy! Anyone bought any particularly nice ones?
