Hi all. DD is 14 weeks, breastfed. She will (usually) sleep for a good stretch at the start of the night in her cot but nearly always ends up in the bed with me at some point. We follow lullaby trust guidelines re safe bed sharing. At the moment I enjoy it and we definitely both sleep better when she's in the bed so not planning to stop any time soon. But don't want to do it indefinitely either - a friend of a friend apparently has a 7 year old who will still only sleep in the parents bed! 
So my question is for those who co-slept: when did you stop and how did you stop?
