If you think comedians are getting younger every year, you might not want to hear this...

Physical comedian Trygve Wakenshaw is to perform a double-act at this year’s Edinburgh Fringe – with his year-old son, Phineas,

Producers concede that the challenge for the New Zealand comic will be not to be upstaged by the youngster in a show that ‘aims to answer a question that has plagued mankind since the dawn of time: what’s more entertaining – a world famous mime, or a standard baby?’

Wakenshaw – who was nominated for the Foster's Edinburgh Comedy Award for his 2015 show Nautilus – will be performing with his son every day at Assembly Roxy, Central.

But Phineas Wakenshaw does not take the record for the youngest ever Fringe performer, as last year’s show Come Look At The Baby invited audiences to watch an anonymous seven-month-old baby on stage for half an hour.
