Breastfeeding latch improved and less gas
Best bottle and nipple on the market. Over night my 5 week old had no gas, slept through the night without gas discomfort, and ate at a pace that mitigated spit ups. I love this product so much I told my sister in law about it within 24 hours of using it. It also has helped with breastfeeding, since he has to work while feeding on the bottle he no longer sleeps on the boob.
