Our first kid who's 2.5 now was pretty easy to keep away from the stove. He learned quickly that stove/hearth = spank and we didn't have an issue. Our 7 month old however who's just learned to crawl is obsessed with the feel of the hearth and stove. He'll shimmy over to it and just touch it as long as he can get away with it. You tell him no and move him away and five minutes later he's worked his way over to the stove again. I may have to put up a gate this winter, at least until he gets the message.
