Oh Lily, that sounds so hard! I think if nothing else was working (and it sounds like you've tried it all), I would just keep giving her the bottle, simply because it means more sleep! I would try to drop it again in a few weeks to see if maybe the phase has passed. I know you are worried about creating a bad habit, but when you've tried everything, I'm not sure what else you can do!

I would take the amount down though- we recently weaned DS off his night feed and before we dropped it we were at like 40ml. I would just get up, make it and give it to him to feed himself in bed (because it was such a small amount I wasn't concerned about this). I was up for like 1-2 minutes- not bad!

I'm sure it will eventually pass- these things usually do! But do what you need to in order to get rest- you need it prepare for your new LO!
