There are a lot of 'you ou ou's in here. This is because he is learning 'I will always love youuuuu' and when he learn something new, he makes the different sounds before stringing it all together. It's quite interesting seeing how he learns.
While unsurprisingly I have taught him many of these words (I don't wander round the house muttering 'I'm too sexy for my feathers), other things he's picked up are the dogs barking, and then getting told off for barking (he does a Pixie bark and then tells her off) and a fair few 'out the ways' which we appear to say a lot!
