A good suggestion that was on the network a while ago (particularly if
you have a gas range): take the knobs off and keep them up high. There
was a horrible case in Winnipeg about a year ago where a
two or three year old who was supposed to be napping woke up, went
into the kitchen, pushed a chair to the stove, climbed up, and turned
on the element. His rubber running shoes melted and stuck to the
element; he couldn't get off.
At our cottage we also have ceiling fans near bunk beds and base board
heaters with curtains hanging on them. I take the knobs off these as
well so that little hands cannot turn them on.
