Bottles for breastfed babies

MaryElizabeth • Pilot wife 💛 Wesley Michael 💙

My son is 2.5 months old, and we have made the switch from 4oz bottles to 8oz bottles. We had several options for 4oz that he liked, but now doesn't want them in the 8oz even with a slow flow nipple. So what is the best bottle/nipple for a breastfed baby?
