The listing, Playtex Vent Air Bottle has ended.
This is a 9 oz. Playtex Vent Air bottle, this bottle also has the original cap to protect the nipple. I tried it with my son once and he doesn't like the nipple. The nipple is straight and has a large round area to be similar to breast feeding. This bottle would be ideal for anyone who is trying to switch from breastfeeding to bottles or is using bottles part-time with breast feeding.
