Hi,
we are in the same situation here, and i am doing what Ali is doing...
we are up to rocking til almost asleep at the mo, sometimes it works other times she just gets really really upset and i have to wait til she is asleep before putting her down.

MJ cries and cries if i just put her in the cot straight away, but had been reading to her when she was in her cot, but that upset her, so now we have her last feed, then go into her room if we dont do the feed there. Next i put her down to play with toys on the floor and i read to her for about 30 mins.
Then i pick her up to rock her... usually she knows this is coming and will protest a little by crying, but generally settles well.
We have been doing this for about 3 weeks now, i am hoping by christmas she will be able to go down herself... so i think i will be doing it a lot longer than Ali, but we will get there eventually
