How to bottle feed a breastfed baby?

Good day everyone! Any tips on how i can make my baby nurse in the bottle? She’s EBF for 6 months and i’m having a hard time teaching her to bottle feed. I’ve tried giving her my expressed breastmilk and formula in a bottle but she refused to take it. I’m a single parent and needs to start working to be able to provide for her but i can’t because of this situation. Your suggestions would be much appreciated. TIA! ❤️
