Windy girl

My youngest daughter has started pulling down her pants and farting on people. She certainly hasn't got this from us and I would doubt it has come from playgroup - the women there are far too nice to be farting on the children - but it has made me laugh (probably not making the situation better). Hopefully it's just a phase - please let it just be a phase. Must stop laughing, must stop laughing, must stop laughing...
