Hi Hun, sorry this is proving a struggle for you

I guess there are two ways of looking at it, would you/could you consider continuing for a while longer, or do you definitely want to stop now? There's no reason to stop breastfeeding at 12 months particularly - it's often 'convention' rather than anything else and if you feel it would be gentler on all of you for now you could hold off weaning for a bit longer, perhaps until any 2-1 related EW/routine bits have been ironed out? (Just guessing from the age that may be playing a factor).
That said, I totally get the wanting to wean and have your body back! So if you definitely do want to I would probably tackle the bedtime first and make use of DH for a while. Either have him do all of bedtime or change your routine around a bit so that it's easier to miss out. For example, we changed our bedtime routine shortly before weaning from bath, feed, story, bed to feed downstairs, bath, story, bed. That made it really easy just to distract and head straight upstairs when we wanted to drop it as she no longer expected the feed after her bath. I didn't replace it with anything, they don't *need* to have bedtime milk at this age provided they are getting a healthy balanced diet with plenty of calcium from other sources or milk at other times of the day.
With the morning I think probably you may have to accept that there may be some upset, though you may be able to help with that by talking to her a lot in the day about how there will be no more milk when she wakes up. They understand more than we think at this age! I would send DH in to resettle until 6am, then if she is upset let him stay with her and reassure/cuddle etc until what you consider an acceptable WU time, then straight up and to breakfast (with a cup of milk if you wish). I think it will likely be no more than a few days of upset, then she will probably forget entirely and may even start resettling more easily at that early hour. I remember I think Anna's LO when she weaned the early morning feed - LO was a bit older but I think they ended up with a few days of the EW being up for the day and then fairly quickly went back to waking at usual time without the feed

Will hold your hand whatever you choose x
