Bottle refusal 9 month old

Ka

My baby is suddenly refusing bottles. She just went to the doctor and she’s perfectly healthy and gaining weight but said she should be having 24oz minimum a day. I can barely make it to 20oz with this child. Any suggestions?

EDIT: she even refuses the bottle when she first wakes up in the morning and I’ve tried lowering solids to see if that works and it hasn’t :(
