I messed my baby up, bad

BTW SHES 13 months she was an NICU baby, brought up on the bottle. She did formula and I pumped (but fed through bottle so I’d know how much she was getting and my supply was/is awful)

At 4 months I started her on the breast. She LOVED IT. I thought it was the best thing in the world. I don’t have much so she still needs bottles.

Anyway, long story short, I messed up. She can’t sleep unless she comfort nurses. She can’t calm down unless at the breast. She’s addicted!!! She still needs the bottle/ sippy cup because I don’t produce much.

She used to sleep in her own crib then, all of a sudden one day around 9 months, she screamed bloody murder/ hyperventilate and threw up if left alone. Now She can only sleep near the breast.

We tried sleep training and routines/ bottles NOTHING WORKS!

I royally messed up by letting her feed off me, now I’m her hostage.

Someone help I’ve created an addict.
