Help! Second baby not taking the bottle

We started trying the bottle at 6 weeks and it seemed like things were going well but then she has not been taking it for the last month or more. She is currently 3 months. Thankfully my parents, who watch my baby when I work, live next door so I can nurse her during the day but come on! My first was a champ with the bottle and the boob and she is just so much more particular. My son would nurse anytime the boob was around and my little lady nurses only on her schedule. Tips? We have tried lots of different bottles, people, positions

Here are my sweet babes
