Breastfeeding Friendly Bottle
I have had good luck with the Mimijumi (google boob bottle!), but have also heard great things about Como Tomo and Adiri.
Both of my girls were/are exclusively breastfed and since we didn't really push bottles on them since I was/am home with them and they didn't need to go to daycare. That said - it's nice for me to be able to get out of the house without a baby attached to my boob the entire time, and we tried tons of different bottles before finding the Mimijumi.
