Is there anything out there other than the Safety 1st stove knob covers? They suck royally! The stupid things just fall off every time I open them. The only other ones I have found you have to remove the knob each time to use. Not much help. May as well just leave the knobs off! I have an old freestanding gas stove and there is nothing to prevent DS from just turing knob and lighting the burners (you don't have to press it in to turn and there is no delay in lighting.) Is there anything else I can do?
