Is it worth trying to make as little eye-contact with her as possible when she comes in - don't say anything, don't engage - just carry or walk her back and put her into bed. Repeat ad nauseum. Every single time she comes in - no eye contact, no words, just put her back into bed. You'll probably have a few hellish nights where you get barely any sleep, and where you may well spend pretty much all night doing this...
...but, the rule of 3 should eventually kick in. Terrible first night, bad second and third night, and then after that, hope for the best.
This isn't foolproof of course, but worth a shot? 3, maybe 4 or 5 hideous nights, and then the possibility of improvement?
This technique relies of utter commitment and tenacious consistency, though. If you give up half way through the third night in a desperate fit of exhaustion, then you might as well not bother doing it at all.
This is just a suggestion, as my 3 year old is a good sleeper, as is his younger sister. They weren't always - but utter consistency was the key.
It's hard to be detached and unengaged, especially when you're desperate for sleep, and especially when that's not how you are with them during the day. But they have to learn that night time is for sleep. They need sleep. You need sleep. Night time is for sleeeeep!!
And a few nights of this, along with lots of the usual love and reassurance during the day, will get the message across. She will learn soon enough - if you're utterly consistent - that there's no fun or reaction or anything to be had from coming into you during the night.
