On my knees trying to wean of breast

[Busheytree]

Hi everyone
Im on my knees with sleep deprivation. I'm 10 weeks pregnant and I have a 16 month old girl. I cannot get her off the boob at night and im looking for suggestions of what to do.
I have tried
Dummy
Bottle
Dad
Music
Shushing
patting
Limiting feed time
Books
Cows milk

Nothing works and she screams until she gets the boob. Last night I breastfed her to sleep and she fell asleep in 5 mins by 7pm. Then woke up at 11 and wouldn't go down with her dad he tried for an hour. Then breastfed back to sleep. Then woke at 3 and similiar scenario. She doesn't breastfeed in the day and eats very well. I really need my sleep with the pregnancy and desperate for some ideas.
Thank you

She is still a baby as well though. Can't you co sleep?

I think I made a similar mistake with my first in dropping the daytime feeds before the nighttime ones. It seemed to make it a bit harder for them to nightwean, well it seemed a bit harder to me. I think ots because you’re not just trying to get her to sleep through but you’re trying to get her to stop BFing at the same time?

One thing I would recommend is Dr Jay Gordon’s Gentle Night weaning method.
