Both help to avoid nipple confusion. Would sucking smoother, the baby might eventually prefer the bottle chest.
Colic actually did not occur, but that does not necessarily lie on Antikolikaufsatz.
Please note:
The small size can hold a maximum 150ml, from about 2 months you have to change because of the capacity on the larger size.
Disadvantage and therefore a star trigger is the sealing ring, which must be in this model in contrast to the naturnah bottles, are used.
The model holds close to nature without additional ring. If you use both models, you forget this ever wasted and possibly precious pumped milk.
That said, I find the Aventfläschchen thoroughly recommended.
