Query: MUST HAVE for frustrated breastfeeding mom

This bottle is beyond amazing.I've tried bornfree, avent, playtex, medela, and gerber. My son treated them like a teether.My son is now 7 months old and was not able to use any bottle until today. My husband fed him quietly in our room with no frustration. Our baby latched onto the nipple and viola! It worked like Magic. Also, he didn't have too much gas drinking from this bottle. Completely satisfied. I can finally have a little freedom.I can see how this bottle will teach newborn how to breastfeed.
