Ok, so I put DD into her own room last night (she has been in her bassinet in our bedroom). put a nightlight on so it was darker than our room (we left the ensuite light on). Fed her, put her into cot and she was awake. patted her for a few minutes then walked out. she cried. went back in and patted her in the dark for 5 minutes and she fell asleep! Woot! woke up twice in the night but went back to sleep! Woot! Woot!
I think we might have been keeping her awake Hopefully it works again tonight. just had to share.

I'm glad I got inspired by this thread and finally did it! There's hope for us all.
