I think the home button is a red herring. Toddlers 'get' it. It's the weird inconsistent in-app controls that they struggle with. Red vs green us also something that kids get early. They know about traffic lights and trains (apart from the 10% of colour-blind boys). It's writing that they find frustrating. Writing should be left for over 6s. I've seen learn-the-alphabet (flash) apps with textual buttons!
