Bottles or no bottles?

I plan to continue to breastfeed my baby girl past her first birthday, but I'm wondering what everyone is doing for bottle feeds. She only gets 1 bottle a day, 4 days during the week and the other days she's on the breast. I've read to change from bottles to sippy cups but the cups my daughter does well with are the weighted straw cups. For some reason it feels weird to think about her drinking it through a straw through 😅 Has anyone made the switch off of bottles yet? Is there really a reason to?
