Happy birthday nature! I hope the take away was worth the wait :)
Still trying gradual retreat, but not sure that it'll work. Last night wasn't great, after 2 hours of sitting with Leah and reassuring her etc I gave up and left her with DH (and drove to the 24 hour asda and bought some shoes as apparently I'm a stress shopper, and it was the only place open). She was asleep when I got home but DH had cheated and rocked her to sleep. She did sleep for 3 hours though, which is the longest she's slept for a while. Woke up around 1am and, after an hour of trying to get her back to sleep, she came into our bed.
Tonight I tried for 2 hours, she mostly screamed at me (not actual crying, just angry shouting) then fell asleep for DH patting her back. Slept for 2.5 hours and has now been awake for 2, she's not happy. I don't think she's capable of self settling, when do I give up?
