I made up a song to sing to Gabriella, words of which are pretty daggy but it went for around 4 verses plus chorus! Chorus was:

Gabriella, Gabriella The most beautiful girl
Who lives in the world, The most beautiful girl.
She has a mummy and a daddy who love her so much
And a doggy called Bonnie who loves to touch...

The verses were about other family members...she seemed to love it! Also used to sing that song from Young Talent Time although I can't quite remember it all now -"Keep smiling, keep shining? Knowing you can always count on me, for sure - thats what friends are for. In good times and bad times I'll be on your side forever more...thats what friends are for"!

As for Alex I just hum along to the tune that plays on his Fisher Price aqaurium thingy.Maybe I will have to make up a song for him too!
