Used these bottles with my first son and it was the only ones he would accept. Bought this set when I found out I was having twins, unfortunately they don't like them due to being in nicu and the nicu used different bottles.
These were so good. I breastfeed for a few months and these were godsent. They were kind of pricey but thankfully I received it as a gift. They worked amazing when transitioning from breast to bottle. My daughter loved it and so did I. I would recommend this bottle every time.
