Jack loves to sing songs too. He used to like me to sing with him but now he says "mummy, stop singing" and just sings himself LOL. And he loves changing the words to songs now - he used to sing "Hey Diddle Diddle, the cat and the fiddle, the cow and horse jumped over the moon.....and the dish ran away with the fork". His latest is "incy wincy spider climbed up the water spout. Then he jumped off and flew away".
