Silicone Avent in 2-piece package

Wide and soft, it has the shape of the nipple, and allows the baby to suck continuously, moving the tongue and jaw as during breastfeeding.
That's why, AVENT it's so easy to alternate breastfeeding with baby bottle.
While the baby sucks, the anti-colic valve of the teat allows the air to descend into the bottle, causing the milk to come out at the baby's sucking rate.
During the suction a slight hiss is heard: this is the guarantee that the air is entering the bottle and not in the belly of the little one.
Ingested air is one of the major causes of crying and irritability associated with colic.
