I'm for teaching them about what they can and can't touch but then letting them have some independence. Really it's because I can't handle the tantrums. ha.
Unfortunately that means putting anything you don't want them to touch very far out of reach! (Yes that means being tidy

)
I have generally let Hannah pull her chair where she wants (it drives me mad but she just wants to learn!) so I would never let her pull her chair up to the oven. That is not OK. But she can pull her chair up to the bench etc and play around. Add some gloves and a scrubbing brush and you'd got yourself a dishwasher!
But seriously... maybe give her some safe things to play with (like the scrubbing brush) and make it clear that the oven/stove is off limits, and put your makeup in a lockable box.
Hrmmm... it's hard to think back to what I did and didn't let Hannah do at that age. But rest assured, they learn pretty fast and the touchy touchy stage only lasts a few months. I can now leave knives etc out (within reason) and Hannah understands that they are sharp and she shouldn't use them without me. (Damnit.. I need some wood to touch!)
