At a loss

So my daughter is 5.5 months. The past month and a half she has been waking in the middle of the night again to eat, no big deal even though I was loving my 8-10 hours of uninterrupted sleep!

Well the last two weeks now she will nurse and fall asleep. I generally give her about 10-15 minutes and then I put her down. Well recently she will wake up within 20 minutes or less and then screams for about 15 minutes. Doesn’t matter how you try to console her she just won’t stop. Once she falls back asleep, she will then generally make it about 2 hours wake up nurse and then ends up waking and I end up letting her sleep on me cause I’m just so exhausted. I’m at a loss and would just love for my child to be able to sleep independently again.

Does anyone have any advice?
