Very interesting. I wonder what response you'll get tonight Wysiwyg?
5:10 - I went in and I said "It's ok mummy's here" (he had climbed up with DD again) he said "mummy get me down" - so a better response but probably not scientifically valid (will try again using 'I' but I am hoping he gets over this climbing around in the dark soon). I said to him "I would prefer you didn't climb up there in the night" and he said "I just made a wish and I was up there"!!! What chance do I have against magic :-)
