Hi there, we were in a very similar situation to you up till 1 month ago - same age little girl too. I was completely over it as i'm also pregnant with #3, DH won't get up in the night to resettle and I was a wreck.

For me, I decided to stop feeding to sleep right before she sleeps but move it back to about 6.45 or so after bathtime and before story time. So instead of feeding in the bedroom, i'll BF her in the lounge then she'll have a story with her sister (aged 3) then i'll take her to her bedroom.

I lie down with her but have her tucked in tight and sing twinkle twinkle at which point she would cry/winge for no more than a minute and then i'd say shhhhh shhhhhh until she calmed. I was amazed that the whole thing lasted less than 5 mins before she was quiet enough for me to leave.

It probably took 3 days for her to get the message that she wouldn't get bf right before sleep and amazingly since then she has slept soooooo much better. she was waking 3 -5 times a night before that and from about 2 weeks after the change, she will sleep through 10 hrs every other night or so. When she does wake, i do go in and feed to resettle but it's quick (and always has been!!).

so maybe for my DD boobies were her crutch and she's now figured out she can settle herself more. I also found just keeping her in her bed has worked too as we were doing musical beds too!

I decided to wait until now to really tackle things because DD has had a really hard time teething so i've waited until her teeth are through and it's been a great change for all of us.

I'm glad I did things gently and respectfully for our DD and it has worked for us. Good luck!
