Bouncing songs? Well, there's the song Pony Boy (which I hope you can find on the net) and this nursery rhyme:

Ride a cock horse to Banbury Cross
to see a fine lady upon a white horse.
With rings on her fingers and bells on her toes,
she shall have music wherever she goes.

You can't keep bouncing the kid indefinitely, so the next thing to do is to look for 'finger plays.'

I congratulate you on having a eleven-month old friend to enjoy and to teach.
