Back from my holiday and just quickly skimmed through a weeks worth of posts!
We have had a massive miracle here in the sleep department. After 4 whole months of hourly wake ups, S has been sleeping so well for a whole week. Mostly waking up twice - around 2am and 6am, but a couple of times has slept right through until around 5 

I've literally done nothing different, it's just happened. I was expecting it to be worse as she was sleeping in a new place and in the travel cot. Hopefully it will continue tonight at home!
Welcome back MrsG and enormouse 
Toby glad your dd is ok. ExH gf sounds like an arse!
Mythree what a stressful time!! Glad DH returned and fed you wine
hope Lucy makes a speedy recovery, how scary 
Million enjoy your holiday. Fx DH's passport arrives. If not, I hope you still have a wonderful time.
Book I would go for the sleep consultant. If we could afford it I would have jumped at the chance. I definitely think it will be worth it as they should identify problems and devise a plan that will work for you, rather than you doing trial and error with different things which I think would be very stressful!
Sorry if I've missed anyone!
