Plan to breastfeed. Do I need to prepare with bottles just in case?

Hello fellow twin parents. I am in my 26th week of pregnancy with my twin girls. (This is my second pregnancy.) I plan/hope to exclusively breastfeed as long as I can with my twins.

I am wondering if I need to get bottles and supplies just in case for the twins or if that’s not necessary. What are others experience with planning on breastfeeding their twins exclusively? Did you buy supplies just in case? Did exclusive bf with twins go well for you?

Thanks for your help.
