Apart from this "forgetfulness", the main advantage of bib 'is the presence of this famous pacifier supposed to avoid, or at least reduced to a congruent share colic by their form close to the womb and a double system valve to prevent air from flowing back inside the baby belly (which is the main cause of colic oh how terrible!). For heavily-used to be my last, their effect seems officially recorded because we have had no problems of that order (well, after all children are not subjected ...). In any case, these teats have clearly facilitated the transition from kindergarten to bottle feeding, and therefore I can only recommend them.
The two handles on them are damn good in terms of size and in terms of grip since with small scratches inside anti-slip material. So, it significantly facilitates the baby by grip and therefore helps to care alone to be fed at will :-)
Finally, the product is really quality, as usual with the Dutch giant Advent industry elsewhere. Just stay this little frustration of not having full scalable kit from the start. This is not really a problem with the product, but more on the packaging. And I stress, it's still a shame ...
