living on the edge

This is the typeof cot that Olivia has in her room. As already mentioned, she can quite easily climb out of it and has done so for a few months now. This afternoon I walk into her bedroom to wake her up from her nap, only to find her asleep on her stomach on the change table bit! What the....?
We are planning to get her into a "big girl bed" by her second birthday, in order to avert a possible head injury not that that will stop her from bumping her head on practically anything, as has been the case since she began walking. Oh well, nerves are there to get rattled - I guess.
