Yes, we tried the ring sling today and Willow settled.
First time I've had a settled baby in just over 48 hours.
Am convinced what we've just been through is a growth spurt, as today all she's done is slept and fed - but her feeds have been really stretched out ... 4 hours, 4.5 hours ... it's been great for my poor nipples.

I so don't get the advice to wake the baby for feeds ... I am doing this totally 'by demand', I really don't see the benefit in waking a sleeping baby.
