Have you tried something like an amber teething necklace? They really do work!

Also maybe give her some time to crawl around on the floor etc to wear her out before bedtime? My Pip was the same - slept through from about 12 weeks until he could move around in the cot.

You could try letting her play in her cot a bit with some soft toys and make it more of a routine - play outside of cot, into cot for a little play then story time and sleep, so it's relaxing for her and not a sudden "stop" to all activity?

good luck
