Baby won’t take a bottle!

My daughter is 3 months old and EBF. I’ve tried since she was 6 weeks for her to take a bottle, I’ve tried everything! Which isn’t an issue I suppose, I am having my hair done on Thursday but my friend is looking after her and will drive to me when she needs feeding. My main question is, when did your baby take a sippy cup ? I’m hoping she will take milk from a sippy cup. How can I encourage her? I’ve noticed she’s started to notice her hands.

I also have a 2 year old so she doesn’t get as much attention as I’d like to give her.
