She will be 6 in the New Year.
It is a fairly elaborate fantasy, which involves a letter from the Queen and a flying horse when she is a 'grown up'.
The letter will invite her to come and live in the castle ("I'll miss you mummy when I live in the castle") - Warwick Castle if you're interested, a green flying horse because her fave colour is green.
She tells she is a real princess, relatives, postman, nice lady in Tesco etc etc
She really believes it, at what point to I gently tell her she's not a princess, she's just bog standard like her mother
I kind of think I should do it before some other bugger does, but it's kind of sweet
