1 month Spoiled at bedtime?

Starr • Selenya Avery born July 24, 2016! 🎀 Angel Baby Lily🌸👼🏼 Secilia Elizabeth born October 15th 2021 🌈💖 Baby #3 Due June 2025! ❤️
So the past few nights she has not wanted to sleep in her bed, she wants to sleep with me, and she has to fall asleep with my nipple in her mouth or she doesn't stay asleep! 
 I breastfeed her until she falls asleep, and then place her in her bed. I leave the room for one minute and she's bawling. I pick her up and she's eating her hand like she's hungry, but I'm beginning to think it's really for comfort this time. (Sometimes she eats on and off for nearly 3 hours) so I've decided not to feed her after she gets up, try to rock her, sing, vibrating bouncer, nothing will put her to sleep almost ever, except my breast. And she'll wake up over and over if she's not in my bed with me. Is she learning this and becoming spoiled or is it too early for that? Im not gonna let her cry in her bed and I don't want to do this cycle of feeding her and  trying to put her back allll night. Help!
