11mo still not sleeping through night

Hi everyone - I'm ultimately desperate so this is a bit of a long post (and sorry for formatting, this is on mobile).

My 11mo has not slept through the night ever - she ranges anywhere from 2 or 3 wake ups to about 7. I haven't slept properly since I got pregnant and it's wearing down on me hard.

Here's some information: - she eats 3 meals a day + snacks - 2 naps a day with a total day sleep of about 2.5 - 3.5 hours - her bed time is usually between 8 and 9pm; any earlier than 8 and she thinks it's a nap - has never been able to drink large amounts of formula at one time and only wants it around sleep time now (so she has maybe 16oz total before sleep) - wakes up wanting pacifier most of the night and bottle at least once - we have a small bedtime routine (bath some nights, change into pj's and sleep sack, drink bottle in bed) - she needs us in the room until she's fully asleep or she screams - she doesn't want to be rocked/held, usually back rubs or just standing there

We have dabbled in Ferber but she just scream cries until we come in, same with night weaning techniques.

Any advice or suggestions would be really appreciated.
