Em - When she wakes at night is she actually crying/needing a feed or just stirring between sleep cycles? My little one wakes numerous times a night (they stir between each sleep cycle apparently) but is able to resettle herself. I found that when she was about 4ish months and woke at night she wasn't actually needing a feed but rather just needing a bit of help to resettle. For her, her dummy did the trick......if she isn't actually upset have you tried leaving her and seeing what she will do, or just trying to resettle without getting her out of bed?

EDIT: Sometimes my DD will wake and even have a little chatter to herself before going back to sleep 15-20 later.....
