The other night we gave Adele a chunk of Celery. She thought this was the bset thing ever. She kept chewing it for about an hour, as she continued to explore and play. If it fell out of her mouth, she just picked it back up and stuck it back in. Better than a pacifier I guess! 
Also, if you need to keep her happy, if anything will do it, a set of car keys will do it.
