Looking for bottle recommendations! We’re currently using the playtex nursers with the drop in liners. They are the only bottle we have that the nipple flow is slow enough for baby. The cost of the liners just adds up and I’m not looking to spend all that extra money! All the other bottles we have say they’re slow flow but they come out too fast! He does breastfeed, if there’s any bottles that are good for breastfed babies and also have a true slow flow nipple.
