Huge reply here, sorry!!!!
I was in the EXACT same position as you when my DD was that age, she is 6 months old today. I think I even posted on here about it.
I was desperate for her to take a bottle so I could get a break at times (EBF) although I always wanted to breastfeed so was my choice. But taking the bottle just didn't happen at that age. She would cry and cry and scream, tried every trick in the book but she was having none of it. I came to accept that that was just the way it was and to embrace it; when she started solids it would be better and could make use a sippy cup. She also wouldn't take a soother/dummy/pacifier.
However, when she started sucking everything in sight, her hands, toys etc I thought I'd give it another go, my thinking that she's enjoying sucking on everything she might just suck on a bottle/soother... low and behold she took both all of a sudden one random day. I would say around 4 months ish. Now she absolutely loves her bottle and gets frustrated if she can see it and it's not quite ready 🙈
So just hang in there, it may happen. I do know some mammas whose babies didn't take to a bottle but only a few.
We're slowly phasing out breastfeeding I think just naturally she wants more and my milk isn't filling her up. We combi feed now with breastfeeding and formula, I never expressed. However I absolutely love feeding her myself, I love the contact and the little snuggles we have and will be gutted when I don't feed her anymore 😢
There is hope, hang in there, stay strong. Just remember that whatever is going on now and other days, it isn't forever and there will be some things you will miss once it's gone 😊
