Finally, after 4 weeks of (not) wobbling his tooth, it fell out at lunchtime, at school yesterday. It didn't get lost at school, but once he got home and played with it in it's glass for a while, it disappeared until this morning when I found it in the washing basket.
So now the Tooth Fairy is scheduled for tonight. He would like her to bring enough $$ for him to be able to by a fruit slushie from the school canteen tomorrow afternoon. Hopefully she is feeling generous, it is his first one after all.
