Yep I agree witht he repetition thing. We have not child proofed our house too much just sectioned off two "escape" areas for the cat. My thought is kids don't learn about the dangers if things are just locked etc.

We do the "ooh hot" thing. We do it for hot drinks and let her feel the heat on the outside of the cup, for the fireplace, heater, oven etc. It hasn't stopped her curiousity so we team the repetition with distraction too and use anything from pots and pans, to toys, books, tv, and even the poor old cat

It means you have to be extra vigilant but for us that seems the best option in our opinions.
