Tommy-proofing products

I though because of Tommy wasn't walking yet, we didn't have to pay much attention to toddler-proofing. But I was wrong! Today, he took a piece of paper I left on the coffee table. He was playing with the paper and went to the kitchen. He stood in front of the stove, which was on, and touched the pot with the paper. He put the paper close to the flame. Thank God, we saw him on time. Lately, we have seen him trying to turn the stove knobs. We always keep our eyes on him because he is constantly exploring, but we don't want to take a chance and we will get more 'Tommy-proofing products'.
