Playtex Baby Angled Nipple - Slow Flow - 2pk

I have one month old twins and we feed formula and breastmilk via bottle. After buying the Playtex variety pack, we discovered that our babies both eat best with this nipple. It seems to be a sturdier construction than the nipples that came with the bottles, and they get a better latch and gulp less air. We definitely have less gas and way less spitup with these nipples. Also, the angle is good when I have to feed by propping up the bottle. Yes...I know you're not supposed to prop up a baby's bottle, but with two babies, and only one set of arms, sometimes it's a necessity. The babies are never left unattended with a propped bottle though. If you're in the same situation, I can say that the angled nipple makes propped feeding easier because the bottle slips out of their mouth less often.
