Tommy's learnt some new phrases. It's quite exciting because for the first time, they're not just words or expressions. He now says 'it's a' (usually car) and 'look at the'. He's also, thanks to teletubbies, learnt to say bu'erfly. He sings too. The song goes 'Tubbies. LaLa.' over and over again. Ocasionally you can convince him to throw in Po but he always goes back to the same. He sung it all the way from Canary Wharf to Seven Sisters yesterday.
