Hi there, (((hugs))), I'm sorry you're so tired. It really is tough to function during the day when you've been up so much at night.
So, a couple things I notice. I do think that last A time before bed is a bit long. Some babies can handle 4 hr before bed, but that's usually with shorter A times during the day. If you look at her day as a whole, it's 13 hr long with that long last A time. She's likely going to sleep a bit OT at bedtime which will likely make that NF habit harder to drop. I know it's not always possible with work schedules, but is there any way you can get her to sleep by 6:30 pm instead? Another option would be to add 15 min on to each of the previous A times, hopefully getting the same nice naps, and then the last one naturally gets shorter with the same BT.
Now for the not so fun part. I really think the only way you are going to get rid of the NWs is to not feed at them all. It sounds like she's developed a bit of a feed to sleep prop. The plan you came up with to only feed after 4 hrs is pretty standard advice. If she can go 4 hr during the day, she can go that long at night. Is she taking decent solids? Does she go to sleep independently? You don't need to use PUPD or shh/pat if they are too stimulating for her. WIWO is actually recommended for SA, but I don't think yours is a case for using it as you're trying to break the nursing prop, not SA specifically. Also, she's pretty young to be a candidate for that. So, what can you do? Find something that helps to soothe her and use it. You might just sit on the floor next to her crib and repeat your sleepy phrase, maybe it's a song, maybe rubbing her back or stroking her forehead. It won't be easy and it will take awhile the first few nights, esp since she's spirited, but I do think it's likely what's going to get the best results.
Here are a couple links that may be helpful for you. Take a look and let me know what you think.
