This bottle is a great idea but it didn't work for us. My baby has been breastfed almost exclusively and we tried the breastflow bottle in our search for a bottle that he could eat from efficiently. It would take him 50 min to take in 4 ounces with this bottle where it would take him 10-15 min to breastfeed. So, I don't think it can be that much like breastfeeding. As a side note, we did end up finding another type of bottle that he was able to empty much faster (Gerber Nuk). Also, this bottle is more of a pain to clean than other bottles because of the extra part. Finally, it came with a storage lid but it doesn't fit under the nipple and nipple ring, so if I were to use this for daycare it would have been a pain to have to bring the nipple separate from the rest of the bottle.
