Tried everything tonight. Her scream is just horrible, it really sounds like she is in pain and she just wont let me comfort her. it just breaks my heart.
Eventually i put her on the bed to re-wrap her, as i put her dummy in her mouth her eyes rolled up like she was already asleep (this always happens but i usually pick her up and pat her/put her in her cot) - but this time i just left her on the bed, leaning over her and sshh'ing. She went to sleep in about 2 seconds.
I guess this is just another technique to add to my arsenal for next time.
