I think this is in the right category for this thread ... it is to do with behaviour and development ...
DS has mastered the fine art of the "Underarm Fart" ... He got the film 'Robots' for Christmas and then has spent the last 2 weeks fine tuning his fart noise skills.
I am sure if there was a World Championship for Underarm Fart Noises my incredibly gifted son would be in the running for the gold medal.
Sigh ... I am so proud
