we're working on using alternatives to NO - the heater seems to have been given the flick now that she has worked out that there is a doorway to the kitchen just beside it - and she can find daddy out there and harrass him! we are doing what we can to explain the danger and then distract her as much as we can, she's too little to really understand the explanation, but we've treated her as a little human with full comprehension since she was born, so we're not changing that now!
