Bottle

Ok so my daughter is officially 2.5 years old and still takes a bottle before bed 😩. She even sometimes asks for it in the middle of the night. I dnt know what to do exactly. She drinks from cups and straws all day but needs her bottle at night to go to sleep. I know it’s all associated with her bed time routine and what she’s used to. Anyone else still give a night time bottle. It’s not even a regular nipples bottle it’s the Calma from Medela which is different. But idk any tips on how to end this?
