Yeah, I've tried it *lots* of times - she'll just have some and then when I latch her off 5 mins later (when she's not drinking) she'll scream again. Or if she falls asleep on the boob then as soon as I lie her into her cot she wakes and it all starts again as bad as before.
Tonight we had a breakthrough though. My MIL sat and read her 10 books(!), then I gave her a feed, then I got DH to come in and I asked her if she wanted more milk or a book. She signed milk. She latched on for another minute (not drinking, just sucking). Then I asked her again. She signed milk

, so I latched her on again

. Minute later I asked her again - and she signed book

. Had a book with DH, then he cuddled her and told her it was sleep time. Turned off the light and she settled with minimal fuss

!
HOOORAH! So we will try something similar tomorrow!
