Negative Positive
Title: Never Again!
Review: I bought these bottles because they were highly recommended by my sister who has 3 youngsters. My son did HORRIBLE ON THEM! He would be so gassy at times he would scream in pain for hours.-The "vent" DOES NOT let air into the bottle so the baby has to release the nipple to let air in so they can keep drinking.-you can not use electric bottle warmers-Assembly UGH!-Pricey!! DOUBLE UGH!!!!I gave EVERY vent air bottle to my sister, my son does GREAT on the disposable bottle liners, no gas, no fussing, HAPPY baby!
