Playtex VentAire Natural Shape Nipple, Medium Flow 2 ea
To prevent a possible choking hazard, test the strength of the nipple regularly by pulling hard on the nipple, especially when the baby is teething. If nipple becomes cracked, torn or shows other signs of excess wear, discontinue use immediately. Do not attempt to enlarge hole in nipple with a pin or other sharp object, as this will cause tearing.
