Now our result.
Positives: Our son needs now only 15 minutes, no longer 30-45 minutes for his bottle and he wriggles when not drink as much rum!
negative: The holes are actually a little too big, too much milk thus flows through.
This our son swallows too much air, among others, must often regurgitation between the drink and spits a lot more.
The holes clog !!! Whether with or PRE 1's food.
Conclusion: Three holes which would have the hole size of the 2 suckers, were perfect and the clogging of the holes is just annoying!
