Has your DH just tried turning everything off, except maybe dull light, laying or sitting quietly, sitting the bottle somewhere she can get it & waiting for her to decide she's tired? If everything is off there's nothing to stimulate her & if she decides she wants the bottle, she can get it on her own, rather than trying to make her take it.

DS & DD2 were like that. Now though they are in a very strict routine. DD is in a single bed too. Everyone in our house goes to bed at 8pm. All lights off & I lay with DD2 in her bed. She'll have a drink of milk in her sippy cup (was bottle 2 weeks ago, but we 'lost' it), then hands it to me when she's ready & goes to sleep.
I've made it clear how it works for mum, but she just seems to let them crash when & where they land! Not great for my routine!! It would be way easier on her too if she'd just do as I say :P

DS was easier than DD2 though. Even though DD2 is more independant
