13 month old and feeding to sleep

Okay, could really use some advise! My daughter will be 14 months in August. We breastfed until 8 months! She started sleeping through the night and I was exhausted. We introduced sippy cups and she does well, our only issue is she some what feeds to sleep. She will get her warm milk while I rock her, head elevated, gets drowsy, and I give her her pacifier (only gets for sleep) and rock her to sleep. I CANNOT her her to take a sippy for her naps/bedtime. I don’t know what to do. They all drown her when she gets tired. I want her off the bottle. Like I said the only time she got it was for naps and bedtime, just like the pacifier. Did anyone else struggle with this? I’m at my wits end, I’ve tried getting her to take her milk early without rocking when I know she’s ready for a nap, then I could rock her to sleep and no luck. If you went through this, please give me tips! What sippy did you use? Thanks in advance!

Sincerely,

A worn out mommy! ❤️
